Preferred Solution: Disk usage constantly running at 100% usage Windows 10

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


As you can see, despite the fact that the usage is only 3.1 mb/s the disk usage says it is at 100% I've read other threads and have attempted multiple fixes, turning off different services, including Background information transfer service, and also disabling many startup programs, also I have tried increasing the allotted size of my paging file, It has gone away at the moment, but I am scared that something will happen due to the fact that this seems to happen allot upon startup, please give me any advice you can. (It appears I didn't have this problem until post windows 8.1 update DX)

A:Running Windows 8.1 disk usage goes above 90% upon startup

Have you looked at process monitor to further pinpoint the image using the disk?

Hi Team,
I have recently purchased a Dell Inspiron 13 5378 2-in-1 model laptop running with Microsoft Windows 10 Home OS and from the moment it has been started, I have been observing extremely slow performance issue being caused by 100% disk usage showing in "Task Manager".
There isn't anything being installed on the system yet, and still its taking ages to open any utility window (task manager, system properties etc.) with really poor performance. I am continuously observing 100% Disk usage without even running anything. This doesn't seems to be an healthy scenario.
I am already done through diagnostics test rub and clean boot, however nothing has helped me.Kindly assist as this laptop is completely unusable for me.

Hey all,
My disk usage is constantly running at 100% and I feel this might be contributing to some recent poor performance in my laptop. Anyone else had this problem or found a solution for it?

Hello guys, I hope someone can help here, I've registered on purpose!

A close friend of mine has problems with the hard drive, I reckon. His disk usage it's always close to 80% reaching 100% several times, making impossibile to accomplish even the easiest things like listening music or watching SD videos. I've checked the processes and eveything seems right, cpu usage is very low. I can't figure out what's the problem. The notebook is new, 2 weeks...

I'm attaching a screenshot of a crystal disk report, it's in italian but you should be able to understand it!



A:Disk usage constantly (almost) to 100%

Hi there
Check out things like -- Page file, Hibernation (Sleep) options, Virtual memory and paging file sizes etc, start up services.

HDD on laptops can be poor performers but that is another issue.

Your computer should really have a minimum of 4GB RAM these days but some machines will work OK with 2GB if you don't want to run more than one or two applications together.

If you are editing large photo files (photoshop) check the use of the scratch files.

I don't speak Italian but from your illustration it would appear that your HDD is a SLOW 5400 RPM one with ZERO cache size which will be a really rotten performer.

I'd swap that for an SSD -- but you need to provide more info of your machine set up first to fix the current problem.

I get a lot of "not responding" in various windows and find CPU usage almost always at 100%. Even with no apps running. The Processes tab in Task Manager shows various processes running but 00 for most of them in the CPU usage column. One or two processes will show 02 in that column, but I don't know how to find out what is using 100% of my CPU.

A:100% CPU usage constantly with no apps running

Hi Joyce,

Have you ticked "Show Processes From All Users" at the bottom of the Windows Task Manager "Processes" screen? That will show you more processes, and possibly what is eating up your CPU.

I recently installed McAfee Virus Protection on my computer. Not long after I started having periods of erratic cpu usage and when I did ctrl+alt+delete I noticed that the mcshield.exe was running extremely high. I google this and found that it could mean that there was a problem and that HJT could help. So below you will find the results of my first run and I hope that someone can help.Thanks.------------------------------------------------------------------------------------------------------------------------------------------------Logfile of Trend Micro HijackThis v2.0.2Scan saved at 5:55:45 PM, on 1/21/2009Platform: Windows XP SP2 (WinNT 5.01.2600)MSIE: Internet Explorer v6.00 SP2 (6.00.2900.2180)Boot mode: NormalRunning processes:C:\WINDOWS\System32\smss.exeC:\WINDOWS\system32\csrss.exeC:\WINDOWS\system32\winlogon.exeC:\WINDOWS\system32\services.exeC:\WINDOWS\system32\lsass.exeC:\WINDOWS\system32\svchost.exeC:\WINDOWS\system32\svchost.exeC:\WINDOWS\System32\svchost.exeC:\WINDOWS\System32\svchost.exeC:\WINDOWS\System32\svchost.exeC:\WINDOWS\system32\devldr32.exeC:\WINDOWS\Explorer.EXEC:\Program Files\Lavasoft\Ad-Aware\aawservice.exeC:\WINDOWS\system32\LEXBCES.EXEC:\WINDOWS\system32\LEXPPS.EXEC:\WINDOWS\system32\spoolsv.exeC:\WINDO...

Hi there.
I'd love some help from you guys into getting to the bottom of this problem.
For about the last 3-4 days my PC has been running slowly. I've been unable to do any online gaming due to this.

Hey guys, I am running Vista on an AMD Phenom X4 9150e with 4gb ram. My hard drive is constantly running and chugging away pretty good too, reading rather than writing i believe. My cpu and memory usage are quite high and my system is running relatively slow for doing simple things like opening a browser. I have attached a screenshot of the system resource monitor with basically nothing running but hijack this and a browser. Any help would be greatly appreciated. I have run scans with malware bytes and adaware, as well as AVG which all come up clean.

Hi there, in the past week, I've started to notice my laptop behave more sluggishly and become quite slow when it would have otherwise handled the amount of applications open etc without any problems.

Scans with antiviruses over the past few weeks have flagged up removed so called viruses/ trojans , so I'm not sure whether this may have lead to my laptop suddenly becoming quite slow?

Every 10-40 minutes, the application I'm currently working in [whither it be skype, L4D2, or firefox] becomes unresponsive, and after a minute or two, the window turns white, notifying me that it's not responding. This unresponsiveness quickly spreads to other open processes, rendering them frozen as well. I can still use the mouse, and it appears rainmeter still responds [updates, showing barely any CPU usage].

Steps I've taken to try and resolve this:
Using only one main program, still does it
turning the computer off and on again
Memtest is clean
chkdisk passes
MBAM/MSE scans return nothing
no memory overflows that I can see

While troubleshooting, I noticed that during the 'fit of unresponsiveness' the disk usage light on my tower is solid, but when I looked at the disk usage in the resource monitor, no processes whatsoever were using it [screenshot related]

If any more specifications are needed, I'll be happy to elaborate.

It could be indexing. What if you turn off indexing just as an experiment?

Hi guys, hope you can help me please. I'm not too computer savvy so sorry if I'm missing something important or I say something dumb. I'm really frustrated and I'm trying my best to learn and solve this problem.
So I bought this Vaio with Core i5-3210M, 4Gb Ram, Windows 8 64 bit. I had really high hopes for it, coming from an i3. For the first few weeks it worked fine, but then it started to freeze while watching movies. Then it started happening all the time, and the cooling fan became consistently noisy for working at full capacity.
I was used to opening task manager on older systems when this happened to see if there was a non-responding program and force it closed, so I noticed Task Manager offers some more features in Win 8. Here, I see that CPU usage is high, staying always around 70% and from time to time reaching 100. At this moment, the process taking the biggest slice is called VCS System Tray with 58%.
What's perhaps more concerning, is that Disk usage is almost constantly on 100%. And by this I mean it reaches 100 and stays there for long periods of time, perhaps up to 20 minutes, then it falls down a few seconds and up again to 100. During this time the computer is excruciatingly painful to use. To even open a program takes forever. When this happens, it seems that Chrome is at the top of the list of processes with most disk usage, with about 1-2Mbps, but this sometimes changes and the list can be led by System, Utorrent, Octoshape, VCS System Tray, Communication...

A:Disk usage 100% running Win 8.1

You can shut off the background process which is responsible for HDD usage.
Obviously the processes running in the background access the data (read / write) and therefore the usage of the HDD increases dramatically.

For example you have installed an utorrent client... this tool shares the data beween in using the internet connection and therefore the HDD is busy

Hello everyone, I've tried to find solution to this problem for 3 months to no avail, hope you guys could shine some light.
Here's the situation, I've bought a MSI PE60-2QE back in September 2015, and I've noticed it is absolutely, definitely, noticeably slower than my old laptop, which should be the case considering this laptop is suppose to be a bit of a powerhorse with I7 5700HQ. Then I've managed to pinpoint the problem to disk usage. Normally whenever i open any application, it will jump all the way to 100% for a few seconds then goes back down when the application is fully open. Sometimes it will also spike to 100% disk for no particular reason. This issue has seriously hindered this laptop performance.
Previously I have also encountered BSOD but since my latest BIOS update directly from MSI official web this issue seems to have resolved. Now whats left is this 100% disk usage issue.

I have an issue that has been happening since last week i think. The problem is that even with the computer in idle the disk usage has these spikes. When i want to play a simple .mp4 file it freezes several times and the all computer freezes when the spikes reach 100 %. I don't know what is causing this issue.

A:Disk usage spikes when nothing is running

Just Windows doing some housekeeping. You would have to use System Internals Process Explorer, to dig down into what process is doing that. If your computer is freezing when playing music. The question comes to mind of what the program is that you are using to listen to .mp4 files.

My laptop is running at about 100% disk use all the time. I've disabled uneccsesary startup items and stopped unecesary services all with no effect. Have updated and run Malwarebytes, Super Antispyware, and CCleaner all of which do not help or show viruses that I can tell. Where do I start in figuring out what is wrong? I'm a power user and run multiple programs at a time and lots of web tabs but even when I ONLY have windows live mail or any one single program open at a time it runs like this with frequent crashes. Just everything is prone to crashing and not responding. I've tried disabling Superfetch, and Background Transfer Service which by searching the web has fixed the issue for some, but I maybe get a 10 minute improvement and its back. I'm wondering if this is possibly Malware?

EVERYTHING is showing 0.1 MB/s or less. There is nothing using a lot of resources yet disk shows at 100%. CPU is about 10% and memory around 40%

Also, I'm having trouble getting programs to UNINSTALL or INSTALL -- just generic failure messages that don't track to anyone particular problem with this going on.

Disk use jumps up to 100% often when

1)I open windows explorer or perform a search in windows explorer for a file
2) I use Chrome or FireFox.

So my C drive (SSD) is acting weird. Task Manager says it's running at 100% but it's only writing 2-5MB/s. The 'writing', as in the pic below is mostly Cortana doing something in Appdata. Before this it was running wild, scanning files with Windows Defender, and System even though no scan was running.

Shouldn't it be waiting until my PC is idle before it starts doing whatever it is doing? Why is is writing so much stuff to appdata? I just threw out my last HDD a few days ago because of a similar issue.. PC was claiming 100% disk usage on my D drive, running all sorts of Windows tasks and a really high response time..

It's been at 100% now for about 30 minutes, at least that's when I first saw it..

Ok, So I figured out WHAT it's doing, looks like Cortana is cataloguing my music for herself, I'm assuming, so that it can play individual songs for me.. Still doesn't explain why it's at 100% disk usage, when it's 'only' writing 2MB/s.

Hello everyone, I've been having a very weird problem recently, in which I BELIEVE is involving high physical memory usage. Sometimes I will be doing things such as playing a game, or watching a stream, and my computer will run fine for a little while. But at random times, my computer will majorly slow down and sometimes even crash. If it doesn't crash, sometimes it will get so slow to the point where I have to hold down the power button and manually shut it down. Every time my computer slows down I notice it is using a TON of physical memory. It's actually happening right now. My computer is going very slow and it's using 6.22 GB memory out of 8. There are no big programs running right now, so I don't understand why it's being slow. I hope someone is able to help. Thank you for taking the time to read this!

Update: I just tried to open chrome, and the computer froze completely. It would not unfreeze. After leaving it frozen for a minute or two, the screen went black. This is becoming very frustrating.

Ok, I am literally KILLING myself over this!

I installed Windows 7 64Bit over XP around a month ago and it was so good that I recommended it to my brother who was previously on XP too. We got him a copy of the 32bit version as he has only 2gb of memory, and he installed it on his machine. However, he constantly had high CPU and RAM usage (Even though no programs were obviously taking it all up in his task manager) and it was making his computer sluggish and slow. Everything was freezing and hanging and it was a nightmare.

I spent a day looking all over the net to find out the problem, but could not fix it at all, no matter what the hell I tried. So he reverted back to Windows XP. (A nice waste of money on Windows 7.) His Windows XP now runs smoothly and is all as it was.

Suddenly today, after my brother connected to my Windows 7 homegroup (or workgroup rather) through his Windows XP machine, my computer got the EXACT same problem as he had ages ago! I have been browsing Google all day downloading s**t, changing things in my computer, trying EVERY possible fix that people have suggested and that sound legit. Nothing works!

So now all of a sudden, my computer is sluggish, games are jumpy and jittery, video rendering times are slooooooow.

Here is a picture of my resource monitor:
You can see the physical memory usage being at 45%. I've ordered the memory usage of each service in highest to lowest.
I just CANT see where the problem is!

A:Windows 7 random CPU usage and high physical memory usage!!!

I can tell you what is probably causing your problems. AVG.
When you are looking at memory, do not sort by Working set, sort by Hard faults.
Hard faults is what causes things to slow down. Plus you have plenty of memory not to worry about usage.

I formatted my computer, and after installing windows 7 again, my physical memory in task manager is very high, and cpu keeps jumping up and down.
I looked at the processes tab, but noticed absolutely nothing taking abnormal memory (private working set.) Then moved on to performance tab> resource monitor, and found svchost (I think it was netsvcs in parenthesis,) hogging all the memory. After ending the process, I still have had high memory usage, and surprisingly, do not see a process anywhere in task manager with high numbers next to it, so I have no idea what's happening.
I have noticed that my windows 7 folder keeps increasing in size, currently about 26 gigs, and a helper told me that it's normal because the updates in windows 7 have a different compression method than windows 8 and after, however when I had previously installed windows 7, fully updated... my folder size was normal, so I assume it can be done?
I originally posted in the Virus, Trojan, Spyware, and Malware Removal Logs section, however I did not find malware on my computer, so unless it's very new malware, I am certain windows 7 is causing this problem.
For antivirus, I am currently using a free trial of Norton.
P.S. This is probably better for the hardware section, but can constant high physical memory, and cpu usage ruin my hardware? I am avoiding using things that take up high cpu and memory right now, and it's currently about 1.2 g... Read more

For some reason, my disk, when i open my computer and at some other point, always spikes up to 100% for a few minutes.
This happens when :

at the start, Something called System and compressed memory always make my pc go to 100% disk usage. Later on, there are all those Service Host going up to 100% and something called RzStatsManager

When i open norton or when i download something new it also goes to 100%, each time I open google chrome too and Steam make the disk go to 100% at the start and every time i open it it goes to 20% and the system memory goes to 80%
All these times, the disk spiked at 100% for a few minutes.

I disabled all my notification, each time i open my PC i disable Windows search and superfetch but it spikes up every time. What can I do?

Hello! I just upgraded to Windows 10 from 8.1 and realized that this disk issue hasn't been fixed. I had some problems with it in 8.1, so this issue is technically a continued one.

Whenever I turn my laptop on, it always runs between 95-100% disk. If I do a quick defrag (takes about 5 minutes), the disk issue goes away; however, I have to do it every time I turn my computer on, or else the issue comes back. What should I do for a more permanent fix? I don't like constantly defragging my computer, since I usually turn it on and off multiple times a day.

Thanks in advance for any help! I wasn't sure where to post this, so I hope I'm in the right place.

A:100% disk usage in Windows 10. Help?

There are 2 solutions in this thread that might apply, here is the one I might try first, after making sure your drive is de-fragmented.

I had this same problem, my lenovo laptop would be left idle for ~15 minutes then come back, 100% disk usage but not tagged to any process.

The issue was a scheduled task to defrag.
Open Task Scheduler -> Microsoft -> Windows -> Defrag
Disable or delete the task.
Hope this helps someone else.
I thought it was hard disk issue as the computer would be unusable without restarting using the power button.

Hi! So ever since I bought this laptop on Dec. 31, 2016, I've always noticed that the service called "System and Compressed Memory" will have a disk usage of 100%. It's unbearable to do anything with my NEW laptop and I've searched far and wide to fix this like disabling superfetch, notifications etc. May I get some help here? I am even thinking of just doing a factory reset if that will fix this bug. I can't do anything with the slowness of my laptop. Even if I'm just surfing the web with Chrome, Disk Usage is still at 100% with "System and Compressed Memory" being the cause.

Since I got my pre-installed laptop my disk usage has been 100% on the system.
I've tried disabling the superfetch and windows search services to no avail. I've read somewhere online that these services could potentially be the cause, sadly that didn't work.

So now I'm installing the windows performance toolkit in order to gain more system information.
I'm running the windows performance recorder.

After it's done I'll update the thread with the new information.

Anyone has the same kind of issue or knows a solution to this issue? Please comment.

Hi All,

I'm not very technical with these problems at all, but I've recently upgraded to windows 10 and fount that my disk usage was spiking up and down to 100% (gradually building up over time)

I thought this was a windows 10 bug, so I downgraded back to windows 8, did a factory reset and everything.

I'm happy at windows 8, for what I use my PC for it's perfectly okay but I thought i'd give it a try.

-I will be able to provide more information later, along with pictures so sorry if this is a little vague, but wanted to get something on here cause it's bothering me! don't really want to trawl through support hotlines etc.

*if there's anything you guys need to help me out let me know and i'll post all relevant information later on

Some game applications that I run, trigger the spike. Just sat on my desktop everything looks okay

I have an alienware X51 - Purchased back in 2012

*Another thing that might be worth adding, after updating to windows 10 I had net framework errors on trying to shut down, these have gone now but I'm not sure if these had anything to do with it? it's all come on from nowhere, my browser seems slow and will crash every so often.

My PC is relatively clean, I have no music, no videos or ANYTHING; just a few apps here and there.

I'm just stuck! I've had a Google around, there's so many different fixes and options; i'm hoping it's something so very simple.

My Toshiba Satellite laptop sometimes goes up to 100% disk usage for no apparent reason. It typically happens 2-3 times per day and for around 5-15 minutes each time. Here's a screenshot of what I'm seeing in Resource Monitor and Task Manager (side by side, respectively):

As you can see, "System" is the culprit here. So the whole "end process" thing isn't going to help me here.

This issue usually happens when I'm playing Minecraft, but not always. The apps I'm using do not appear to impact the duration or frequency of the issue at all, but if it helps I generally have Skype, Minecraft, and Google Chrome open. Sometimes, this issue occurs when I have nothing but a webpage open. Closing apps does not appear to help.

My laptop's otherwise in great shape; I treat it well, update whenever it asks me to, browse carefully, etc. This has been a problem since I bought it a year ago and has neither improved nor gotten worse.

Anyway, I spoke with someone tech-savvy about this and she said it's a "known Windows 8 issue" and that there isn't anything I can do. After several updates, however, this is still a problem. Any information would be nice, including an explanation of exactly what this mysterious "System" is doing.

Thanks in advance!

A:Windows 8 - 100% Disk Usage

In Resource Monitor, put a check mark by System to filter the entries in the window below. Then in the windows below, expand the column that shows what is being written to or read from.

Do you see anything that stands out? Does the list slowly shrink as the process continues?

Have you tied it to an event, such a time of day or time between occurrences? Do you ever leave the machine idle for a period of time and if so, does it go into any type of maintenance process?

First go to Disk Clean up right click and run as Administrator and when it's done place a check next to everything and clean your system (it can take quite a while). Then go to Defragment and Optimize Drives and defragment everything... shut down(not restart) and reboot 3 times This cleans and organizes your disk. The 3 reboots lets windows put all programs and start files to the beginning of your C: drive on the outside of your disk.

Hey, hopefully some1 can help out a little.. I've been researching this for probably 2 months now. I get 100% disk usage spikes constantly regardless of what I'm doing I.E.: open file explorer, IE, Control panel, Changing songs on Spotify, ect. Now I have tried troubleshooting this issue several times including actually shipping my Mobo and PSU back to their respective factories thinking it was a hardware fault - b4 I go too far here is my rig

OS: Windows 8 64-bit
Cpu: AMD FX-4130
RAM: Kingston HyperX Performance 16.0GB Dual-Channel DDR3
Motherboard: ASUSTeK COMPUTER INC. M5A97 R2.0 (Socket 942)
GPU: 3072MB ATI AMD Radeon HD 7970
Hard Drive: 1863GB Seagate ST2000DM001-1CH164 (SATA)
PSU: Corsair TX650

I have tried updating all the mobo drivers, changing out SATA cables.. even changed out the hard drive - nothing has worked what so ever. In fact I am still getting spikes in safe mode w/o networking.
Also I have tried re-installing W8 and still getting this issue.

A little more info on my RAM so you guys can actually look at it - Just google KHX21C11T2K2/16X and it should come up with exactly what I have. Also I have run http://hcidesign.com/memtest/download.html which is just a RAM test and all seems fine - No errors + I had borrowed a few sticks of DDR3 from a buddy so we can essentially rule out hardware.
If you guys/gals need anymore information please let me know I will provide w/e is needed.

Hi there, I encountered a problem a few weeks ago after I refreshed my laptop when it started refreshing the desktop constantly to the point where I couldn't do anything. After the refresh, the desktop was back to normal, though I noticed my disk usage in the task manager was constantly at 100%. I've been troubleshooting this problem by upgrading from Windows 8 to 8.1, I've run chkdsk.exe /f /r, I defragged the disk, ran a virus scan, etc. The only thing that helps this is disabling the service 'superfetch' and/or 'Windows search', though the problem can still arise after doing so. Every now and then the disk usage goes back to it's regular 2-8% but then randomly shoots back up to 70-85-99-100%. It's causing some occasional slowdown and I have no idea what the fix is.

Here's a screen cap of my resource monitor when it's at 100%:
And here are the specs of my laptop:
-Model: Acer Aspire V5-552
-CPU: AMD Quad-Core A10-5757M @2.5GHz

-OS: Windows 8.1

Please help me resolve this as it's driving me nuts trying to fix this once and for all.
Thank you in advance.

A:Fix for Windows 8/8.1 100% disk usage?

I would probably put a check mark in the svchost.exe (LocalSystemNet...) entry in the Resource Monitor and see what it shows as being used. Maybe that will give you some insight. Mine only runs occasionally and seems to be writing to a log file and one other thing.

Since I don't use OneDrive, is yours set up to sync, are you using the Microsoft user ID for your system or a local user?

Hi all,

My laptop has been progressively getting worse with its responsiveness after startup. Icons take ages to load on the desktop, programs launched are lagged or sometimes fail to respond. The culprit is 100% disk usage that lasts for almost 5 minutes after a boot. Unfortunately, this disk access seems to be spread randomly among multiple programs and services, meaning I can't isolate what specifically is causing these massive spikes that are crippling my computer after startup.

Things I've tried:
All the latest Windows updates as of December 10th.
Full scan with Malware-Bytes detects no viruses.
Ran CCleaner on the registry and cleaned up unnecessary files.
Disabled Superfetch as a test, saw no improvement.
Checked the SMART readings on the drive, everything showing as "Good."

The lack of responsiveness reminds me of an old Windows 95 install chugging along after a few years. It's really quite bad and I can't isolate it at all since it's spread among a ton of services.

I don't have many extraneous programs installed, nor any real-time anti-viruses besides Windows Defender. Has anyone else experienced this problem lately with Windows 8.1? Eventually the disk access settles down but I feel like load times are still poor... even browsing folders after the disk access goes down, icons don't load instantly, but I see them load over time. Just a sense that everything is not running up to speed. :/

Thanks for any help or suggestions people may have.

A:Windows 8.1 100% Disk Usage

i had the same problem with mine it was a combo of services trying to catch up to there tasks all at once, had performance set to programs( the background stuff took 5 times longer to complete their tasks) to many start up items and other services i didn't need running. i set all the auto maintenance tasks to run when i'm not on and changed services to manual if they were not needed at start up( try 1 by one so you notice if it affects anything and check the dependency on other services in it's property menu).

Then there is the paging file i'm not sure if services use it but you would think if say defrag was running and something started that required the page file on the same disk then times that by how many are lined up to do there task, i had 15-20 backed up at a time with 100% disk use for 10-20min after boot.I also had a problem with the services that run the search function not starting to top it all off. But with the performance setting in my opinion the quicker the background tasks finish what they have to do the better and i think i seen a setting that makes them run 1 at a time.

I run a desk top now so there is plenty of resources to go around but my old HP DV6, Which actually run good now after i fed it a copy of boot n nuke and done a fresh Win 7 install is now my test computer for things i dont want on my better one it even has it's own live lunux and Win 7 usb with a lan cable to the desk top to keep it clean.

Hello all
My wifes work computer seems to suffer from a disk usage bottle neck. Most of the time its tje indexer. Does this service need to be active to search properly? Also i was under the impression that the indexer doesnt run while the computer is in use. Is this true and could there be any other culprits causing this?
Thank you

A:windows 8.1 100% disk usage.

Indexing will make some searches faster but no, it is not required. In fact, I never use Windows built-in search function. I use "Everything" search (http://www.voidtools.com/). It's free (donationware) and absolutely outstanding.
Having said that, the indexing service shouldn't run at 100% cpu (I assume you mean cpu usage and not disk usage). Go ahead and disable it and see if the problem goes away. But you might also want to run full scans with both your installed anti virus app AND with MalwareBytes.

However, when installing Windows 10 to a SSD it appears to be absolutely fine, disk usage is under 20%.
