WinSXS Folder not actually consuming lots of space

Q: WinSXS Folder not actually consuming lots of space

I've seen a recurring post on many forums discussing the absurd amount of disk space being consumed by the C:\Windows\WinSXS folder.

I've done some testing in house to confirm the fact that the files in this folder are predominantly hard links to a small number of files and it's not really taking up anywhere near the space that Windows Explorer is reporting.

Here is a link to better explain what I am talking about:
WinSxS Disk Space Usage: It’s Not What You Think (David's Blog)
Here was my conclusive test:

1). I took a virtual machine and created a new 200MB hard drive that I assigned the drive letter E:

2). I created a subfolder on E: called WinSXS. So, I had E:\WinSXS

3). I copied in a 13MB zip file into E:\WinSXS.

4). I then created 20 hard links to that zip file with the command shown in the link above (mklink /h hardlink#.zip original file

5). According to Windows Explorer, E:\WinSXS is now 267MB in size.....even though the entire E drive is only 200MB.

6). From a cmd prompt, running dir on E:\ shows 174,543,872 bytes free.

Therefore, tools like Windows explorer and TreeSizePro will report that that WinSXS folder is consuming massive amounts of space....while the true fact is that the folder is being misrepresented because the reporting tools do not understand the difference between hardlinks and real files.

Preferred Solution: WinSXS Folder not actually consuming lots of space

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.)

A: WinSXS Folder not actually consuming lots of space

Sorry for dragging up this old post, but it answers a question I've been searching and searching for an answer to. I can confirm that on my system, when I add up all the root directories on my main hard drive then subtract the "size" of the WinSXS folder, I get the reported used space in the properties of my boot drive.

Thanks pparks from ending this tail chasing!

Hi is there any way I could free up some of the 15GB of disk space on my Vista computer that the C:\Windows\winsxs is taking up on my computer? I won't just go in there and delete stuff as I'd read in many places that that shouldn't be done. So what is the right way to get rid of stuff in there that isn't needed anymore? I've seen that there are files there from old versions of things that aren't needed anymore.

Thank you in advance!

A:winsxs folder taking up too much space

Hi i am having problems with low disk space on a windows 7 network machine. I ran various programs such as tree view and windirstat, and i gather from this, is that the winsxs folder is taking up mass amount of space as its like 10gb..

I have used the command (DISM /Online /Cleanup-Image /SpSuperseded) to try and reduce the size of this folder. but i get a error " Service pack cleanup cant proceed: No service pack backup files were found"

Any Ideas Please?

A:Low Disk Space (winsxs folder)

The winsys folder is not really as large as is reported by various programs. It is made up of mostly junctions/links that take up no space and point to other areas on the drive.

The files size programs are really seeing the size of the files that are being pointed to by the links and are not accurate.

Trying to reduce the apparent size of that folder will create problems for your system.

I would look elsewhere for files to eliminate.

I am running and IBM T40 laptop with WinXP SP2. Over the last several months, the performance on this machine has been slowly degrading. I run Norton Systems Works and am quite diligent about keeping things up to date. I run full scans every few days. I keep disks pretty free of clutter using Norton's CleanSweep. I run FireFox with privacy settings to trash everything at the end of a session. I also run SpyBot, AdAware and SpySweeper once a week (but none are "active" all the time). For that I run AVG's new spyware appl (was ewido). I was running SpySweeper before AVG for real time protection but found the SpySweeper would periodically take 60% of my CPU for minutes at a time about once every 30 minutes.

The most recent problem is csrss.exe. It has "suddenly" started consuming 20 to 30% of the CPU when ever I run certain Excel applications (no graphics). What makes matters worse it that it appears that AVG's guard.exe fires up as soon as csrss.exe does, consuming another 20% or so. I have never noticed this before, but ??? I know that there is a trojan/virus version of csrss.exe, but none of the protection tools I run have found anything.

Any thoughts on what I might explore, try, etc? I am about ready to reload the operating system and start from scratch.

A:Csrss.exe Consuming Lots Of Cpu Time

It seems to depend upon where csrss is located, whether or not it is a needed Windows process or malware. The location for the legitimate process is:
C:\Windows\System32 folder. Even with "high priority" the consumption seems high.

Since doing a fresh install of Windows 8 Pro RTM x64 English on my Sony Vaio Z21 laptop, I've been bothered by a sudden increase in fan noise whenever I leave the machine idle for a while and the displays are turned off. Finally decided to try and get to
the bottom of it today, so I ran the Performance Recorder with the CPU usage profile enabled and brought up the relevant graphs in Performance Analyzer. See the below screen shot for the results.
I started the trace and then left the machine alone for a while to trigger the idle behavior. It's pretty clear that Dwm.exe is the main culprit. As to why this process would find anything useful to do when all the displays are turned off is beyond me. Also
Outlook.exe sees a significant increase of CPU usage during the same time period. Whether these two are somehow related, I have no clue. Please note that I've disabled all other processes in the graph for clarity; no other processes showed any visible increase
during the trace.
Any advice would be greatly appreciated!

I just noticed today that in Windows Task Manager, I see 'svchost.exe' consuming lots of memory (Task Manager reports 265,376K). I look at Task Manager a lot in order to manage memory in general (there's only 1GB on this box), and I've never seen a 'svchost.exe' consuming this much before. It grows until available memory [under 'Physical Memory (K)' in the Performance tab] gets down to under 10000, and the machine slows to a crawl while it furiously swaps.

I fired up "Process Explorer" (Sysinternals), and I can see the offending 'svchost.exe' hanging underneath 'services.exe' (along with plenty of other services). Sometimes, the offender has 'AcroRd32.exe' or 'wuauclt.exe' hanging off of it (but the child processes don't consume anywhere near as much memory as 'svchost.exe').

When I mouse over the 'svchost.exe', it shows...

This may be an old one but couldn't find any ready answers to fix it. I am running out of disk space on my OS drive and having run TreeSize, I discovered that the WinSxS folder is taking up over 11.5 GB. Has anybody ever found a solution to this problem?

A:Too much space on OS drive being taken up by WinSxS

What problem specifically?

Have you done a disk cleanup to get rid of temp and other unneeded files?

Winsxs is not where I would try to generate space.

How much space do you have devoted to System Restore?

Have you turned off hibernation if you don't use it?

I currently have 20GB free space of 221GB after using Disk Cleanup and CCleaner and deleting some files.

I decided to download WinDirStat because I felt like my hard drive space was just disappearing all the time. (I got this computer in 2008). And it showed that WINSXS folder size is 136,0 GB!!! Which makes sense because I have 20,9GB of music, 5,70GB of pictures and files + some programs and maybe 5GB of games.

I Googled about Winsxs and read that I can't delete this folder.

So my question is why is it so big (usually this folder is 5-10GB to some people?) and how can I decrease it?

EDIT: Winsxs is 136,0 GB and ManifestCache is 126,2 GB ?

10% of my entire SSD space has been consumed to save old worthless files I have no interest in. How about a "choice" Microsoft? God, what is it that Microsoft doesn't like about offering us choices?
"Attention User: We are about to upgrade your system to the latest build. Would you like us to A)delete your old build and re-install fresh or B)Keep the old buggy outdated build on your system and have it consume lots and lots of valuable space?". I'm thinking option A? What the hell?

"We didn't want the user to have to make a choice". *sigh*

I should just format my SSD and install the new build myself. But Microsoft thrusts it upon me before I even knew what was happening. This is not the first time I've been thrusted upon by Microsoft.

Running Vista 2000 SP 3 on an older PC. Just installed Norton 360 and clean things up a bit. Have a 500GB drive that was about half full before the Norton install. Went down to 25MB in a day. No unusual activity save for copying 100ish GB of photos onto a thumb drive.

I have deleted more than 1.5 GB of stuff and verified that the drive reflected that reduction in properties. It did. Then over the next half hour it filled back to 25mb left.

I have done all the obvious: compressed, cleared recycle, "cleaned" the disk. Again, this is not an issue of removing files. Something is consuming space. It appears to stop at 25MBs - which makes me think that there may be a virus - but I JUST installed and updated Norton and went through all that .... so I am befuddled.

run disk cleanup [programs/accessories/system tools] and check everything

I've recently been plagued with a pretty severe virus, which while i thought i had it mostly under control has covertly been filling my hard drive. I'm almost positive i've tracked down the offending file (C:\windows\system32\logfiles\wmi\trace.log) which is over 7 gigs. I'd like to just delete it but I'm not sure of the repercussions and doubt that this will stop the source of the problem.

Here are symptoms of the virus so far:

Unable to access task manager (fixed by manually altering registry)
Intermittent trojan adclicker/loader attacks (consistently deleted by synmantic)
Constant attempts made to alter registry item {192937EA-D3BB-45F5-9B33-ED6C3C358672} by "ec526bfb" (blocked by Spybot TeaTimer)
Spybot is unable to completely remove Virtumunde due to its being in memory but running at system startup yields same problem
5+ gigs of disk space consumed (C drive is listed as 0 free bytes)
consistent single popups in internet explorer
at starting of windows there are a number of blank cmd prompt windows which cascade slowly across the screen

there's probably more things which i haven't discovered yet... i have the system restore discs but only want to use them if my only other option is buying a new laptop. any and all assistance is greatly appreciated.

Just today I got a notice my SSD was getting too big. Taking a look further, it seems the culprit is winsxs file. I've had this computer for 4 years and have never seen this. It is 35gb in size, that folder alone. What is going on?

A:Winsxs suddenly taking up 80% of disk space

Take a look here: https://support.microsoft.com/en-gb/kb/2852386

When you install updates, Windows keeps a copy of the original files along with the newer files. Those copies are located in the WinSxS folder.

Note: If you run the Windows Updates cleanup you may not be able to roll back installed updates (if you need to) without reinstalling them first.

I have a Acer Aspire 5315 laptop that is going on three years old with Windows Vista Basic. The computer has an 80 gig hard drive with two partitions split evenly. After a while I noticed it continually consuming more hard drive space on the C drive when no new programs were being installed. During regular use during the day (checking email from Gmail) I started getting prompts that the computer was running low on hard drive on C drive. The computer had 2 gigabytes of free space on the C drive initially. I rebooted only to find out that windows didn't give the space back.

I have tried doing a hard drive clean up with only marginal success in reclaiming part of the initial 2 free gigs on C drive. I have tried registry fixing programs like Reg Cure and other system tune up programs like System Mechanic and the problem continues. The laptop initially came with 1 gig of ram I have upgraded it to 2 (the max the laptop can take).

I noticed the problem started to happen after I had to use a restore point to fix a driver problem with my printer. Any suggestions of what to do is much appreciated or even what to try.

I had heard that laptops have a recovery console that may fix this this problem that resets it to factory defaults. Further information on this would also be useful.

Thank you in advance for any help!

I have an ultrabook with 128 GB of space, 101 GiB after partitioning and so on, so it got annoying when I just checked my C:\Windows directory and it was up to 25 GBs, with winsxs up to 14 GBs. I had heard on Windows Weekly that there was a way to clean up the winsxs directory now, so I followed that simple procedure and gained 3.5 GBs of disk space after the utility was done. I then rebooted and I gained 1.5 GBs more, 5 GBs of unnecessary files removed.

C:\Windows is down to 18 GBs now and winsxs down to 7.3 GBs, with the disparity between the 7 GBs less those folders report and the 5 GBs less the system disk reports no doubt because of the hard links in winsxs, that have been mentioned here before.

I've seen several threads here about large winsxs folders, but none mentioning this recent blog post from Microsoft so I thought I'd post this fix that worked for me.

A:Large Windows and winsxs folders taking up too much space

The large size of the winsxs folder is more apparent than real. Actually most of these files are just links to files that are stored elsewhere. Something like shortcuts but not the same.

Since Windows 2000 NTFS has had a feature where a single copy of a file can appear in multiple folders. But it was not until Vista that Windows used this feature, which it does for the winsxs folder. This saves considerable disk space but makes the determination of disk space used by a specific folder very difficult. It is not that the properties dialog is lying to you (as some have suggested), it is a question of what is the truth. There are no easy answers to that question.

The method used in the article should be safe. But there are some more radical methods from other sources and these should be avoided.

I recently replaced a 60GB SSD because my winsxs file was using over 25GB and I was down to about 8GB of usable space. I went out and bought an 80GB SSD and after my install it was already half full before I put any application on it. The winsxs file is already at 11GB and I really do not want to get into the habit of re-installing my Windows 7 Ultimate 64-Bit system every 6 months. I also run a 64GB Fedora system on a 60GB drive and I'm not even close to using half of it. Why is Windows 7 so demanding on disks? Is there anything I can do to trim that down as I feel it will be 20GB in a few weeks. I'd like to maybe run an OS on Virtualbox but it is not looking good. Any suggestions?

A:Winsxs/pending.xml files taking up all disk space

Winsxs is not a normal folder it contains symbolic links to files that are actually located all around the system folders - unfortunately symbolic links are designed to report size and other information to windows explorer as that of the endpoint files not the few bytes that the links actually take.

If you look at the winsxs folder as it really is then you would see an actual size of less that 1% of that reported by File Explorer, so to clear this folder you will need to uninstall the programs that are generating the linked files and then performing a disk clean-up

I know there have been many prior threads on the WinSXS folder. On my 32-bit Win7 machine, I just completed running Disk Cleanup in Administrative mode after installing KB2852386 (the update for Disk Cleanup). This is what my folder currently looks like running WinDirStat just now:

Is it possible to remove some of these files and regain disk space or is this 6GB WinSxs folder as small as it can get?

Thanks for any guidance.

A:WinSXS folder - 6GB - does this look right

Only 6 GB? Mine is somewhat larger than that.

But actually things are not as they appear. The NTFS file system has long had the capability for a single file to appear in more than one folder. That is the situation here. While the folder appears to contain 6 GB of files a large number of these are actually stored elsewhere and counted twice. Even if you could delete all of the files in WinSXS you would not save 6 GB.

So, a few years ago in installed windows 7. I had xp up till that point. So, on thinking like a rational person would... I knew that i didnt need an exuberant amount of space for Windows...

Winsxs is best left alone.

14 GB is not outlandish. Mine is nearly 12 and I have a tidy system.

I have a system that I set up with two drives; a main SSD and a standard HDD. I used Sysprep to move Users and ProgramData to the larger, slower HDD to preserve the SSD. I realized that most of the writing to the SSD now occurs in the Windows folder, specifically the winSXS folder.

Is there any way to move this folder? I am scared to try a junction (I tried that once with Users and it was a disaster).

Any ideas?

A:Moving the winsxs folder

I would suggest against it. Actually the biggest writes to the drive will be the system restore information at this point. Most the other stuff is system logs and they are tiny little text files. Not enough activity to get upset over.

I need to delete some WinSXS folder entries, no questions asked. How do I do that?

Taking ownership and rights isn't enough it seems. The last won't work on all folders inside WinSXS. I keep getting errors when applying rights for my username over these folders. "An error occurred.... access denied".

I do not need system stability. I just need to remove some folders is all.

A:I need to delete some WinSXS folder entries

Hi there
Some of these are system files and symbolic links - not sure why you'd want to delete these. You will probably break the system deleting a load of these.

Download a program like TREESIZE to check if you've got a load of files in say your user directory you can get rid of or check all windows.old type files from any previous windows installation - these can be deleted. Check also temporary internet files etc.

If you really can't get any more space back get a larger HDD -- they are incredibly cheap these days - even for capacities of up to 5 TB.

Hi All,

I have Windows 7 Ultimate 64, and found out that the folder "winsxs" contains besides "backup" folder also more than 21,400 folders with about 9GB of files. Are those files really needed?

The WinSxS is not as large as it "appears" to be; See this excellent post by Barman58 for an explanation.

I downloaded WinDirStat because I felt like my hard drive space was just disappearing. My hard drive capacity is 142GB. I bring this up because I only had about 5GB left to work with. I cleaned it up pretty well getting rid of a lot of old temp files and some other stuff. I now have about 40GB of free disk space. I've been reading the forums and everybody seems to be saying not to remove any files from winsxs. I feel like 13.5GB is a lot considering people think that their same folder being 4gb is a lot. is there any way at all that I can clean this up without breaking applications?

A:C:\windows\winsxs Folder Size 13.5 GB

Hello and welcome to the Vista Forums!

I have got quite a lot of say! First and foremost, that size is incorrect! The Windows Side by Side configuration stores a lot of duplicate files, exactly the same. However, the other copies are only hard links to the first copy, and don't take up any additional space. Those first copies may not even be in there anyway, and may point to somewhere else again!

Hard links are used to link these folders. These are far more robust than shortcuts or symbolic links. They show as the full size in Windows Explorer or WinDirStat. My point is that your file size is not 12GB. Microsoft always quote 400MB of actual data taking up space as manifests, first files, etc. etc. Your folder is quite large, so perhaps you are more around the 600MB line.

You can get some more general information here: Demystifying the WinSxS directory in Windows XP, Vista and Server 2003/2008 - Aaron Tiensivu's Blog

Sadly, you cannot delete any of it, and it is very difficult to shrink. The best you can do is run vsp1cln from a Command Prompt to remove some pre-SP1 stuff. Note that you can now no longer uninstall SP1, although this shouldn't matter too much, and you cannot then get pre-SP1 hotfix corruption replacement files out of it either, although that should matter even less.

If you have any questions, do not hesitate to ask!

Hello all!

First off, I'm sure this has been asked a bajillion times so let me get it out of the way first. IS THERE ANYTHING that can be done about the redonkulous size of the Winsxs folder? I had a problem with Harddrive space (when my HD was 20 gigs large) and figured it was just...not enough space. I repartitioned my drive (and ended up corrupting a lot of my music and video on my media partition in the proccess) and reinstalled windows vista 64bit giving it a whopping 40 gigs of space to work with. To my surprise I got a window pop up saying "LOW HARDDRIVE SPACE!"

I figured it was due to having 2 iphones and a back up for each. I got rid of one, and found I still had this problem. 40 Gigs with 35 programs on my program list (most of these are pluggins and such, my biggest programs are pinnacle studio 12, adobe photoshop, adobe flash player, pinnacle studio pluggins, and Google Chrome. The next thing on the list is Itunes in size order.)

So before I ask my next question, what can be done for this problem outside of compcln and vsp (which have not helped at all!).

The big question is...Where do I go from here? My next idea was to move the folder to my other partition witht he advice from


But the next issue I ran into was...i Never reinstalled burning software to free up space on my other drive. So should I go ahead and just reinstall windows and try and repartition my drive? If so,... Read more

I did a system restore recenlty and I'm using Comodo Defense+ as HIPS.

I had an old rule (before system restore) for ...\system32\taskmgr.exe and when I tried to open task manager using cntrl+alt+del it requested a new rule for the file .../winsxs/blablabla/taskmgr.exe.

It actually runs the taskmgr.exe from the winsxs folder and not the system32 folder!
And it happens also for others system32 exe files (SystemPropertiesProtection), but still many ...\system32\*.exe files run from the system32 and not the winsxs folder.

How do u explain this? Is it good or bad? Do I have to fix anything?

Thank u!!

A:system32\*.exe files now run from winsxs folder!

Hi PiCoPi. . .

Welcome to the Tech Support Forum - Vista!

The "sxs" in the folder \windows\winsxs stands for "side by side". This folder allows programs to use different versions of the same file, usually drivers. Files in winsxs do include executable files such as Task Manager (taskmgr.exe) and System Restore (rstrui.exe).

A reason that Task Manager would be executed from the folder c:\Windows\winsxs\x86_microsoft-windows-taskmgr_31bf3856ad364e35_6.0.6xxx.16386_none_122b6d31ac48dff3 may be due to corruption of the \windows\system32 file. Check to see that the file sizes and dates are the same. I have posted a screen shot of my Task Manager files for you to review.

You didn't mention the reason for running the System Restore. I suggest that you run the scan and repair utility found within your system. Perform the following:

click on START | type cmd.exe in the Start Search box | right-click on cmd.exe | select Run as Admin

In the screen that comes up type the following:

sfc /scannow (space after sfc) - press ENTER

This program may take 10 or 15 minutes to run. Good Luck to you.

Regards. . .

All my winSxS folders are in a windows folder in a file under a folder called Syst79761AE4.   
Now, there are two windows folders on my computer: the regular one containing all the windows files, except for winSxS files which are stored in a different windows folder under Syst79761AE4, instead of just under the regular hard drive C.  My antivirus program (BitDefender) also cannot scan the winSxS files, and says the objects were not found after the scan has been completed.

I ran an Avast! virus scan because my computer was slowing down (significantly). It found 91 infected files. All in the winsxs folder. I then deleted them. I really really really shouldn't have.

Now, Windows Update will not work (error codes 80073712, and 80070002). One of my games will not work, and several other applications will not work (usually with a "missing gdiplus.dll" type error).

I tried a system restore, but there was no option to restore to a point prior to the date I deleted the files. sfc /scannow in the cmd did not fix the problem. I tried restoring the individual folders in winsxs but they don't have an early enough version either.

I tried using a file undeleter to see if I could recover the missing .dll files. When I tried to run the program, I got a missing .dll file error. No they're not in the recycling bin. Basically they're absolutely nowhere on my computer.

Attached is a sampling of what I deleted.

After looking around I believe I should just use a Repair Install. I'm using the .iso from here because I have a factory install and don't have an installation disc. Is this the correct course of action? If not, what is?

A:winsxs folder missing files

And now I got a 80004005 "disc did not burn correctly" when trying to mount the .iso file. Also, I'm now out of blank CD's that are large enough.

So I just found out about this folder and was looking into ways to clean it and how to keep it small. Mine is about 10GB and I was curious as to how large is normal for this folder. I know you can clean it by using compcln.exe but I ran that already (though I had to shutdown as everything stopped working while I was running it and everything was stuck for 3 hours) and now I cannot run it again. Bascially, I want to make sure it did its job so if 10GB or so is normal then I am going to keep it so I don't have to reinstall the whole system. My system was RTM, so it contains all updates from the very beginning, except for the service packs which I tried to delete with compcln and I am now running SP2.

I used to be able to access an option in the Disk Cleanup tool (cleanmgr.exe) to delete old Updates files. Now, the tool merely scans for updates but does not display the appropriate checkbox. My winsxs folder is growing out of control. Installing a couple of recent updates (like 1GB of Office updates and a new 400MB driver package for my video card) is slowly eating away the remainder of my SSD.

The longest scan in cleanmgr is for Windows Update Cleanup, and I know there are a lot of updates to clean, but there is no option at the end of it to do anything about that.

There should be a checkbox in here for the updates. I was able to do this before and save 7GB in one bang, but now there's no option anymore and I have no idea why.

Where the heck is this tickbox?
