Preferred Solution: Unable to install Windows Updates, error code 80071A91

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.)

Hi - welcome to the forums!

Hmmm - Invalid Class error - that's a VERY rare error in your MGADiag report.....
It appears to be caused by a broken WMI store.

Please run the following commands,

Net stop winmgmt /y
Net stop wscsvc
MD c:\wmibackup
DIR %systemroot%\System32\Wbem\Repository
MOVE %systemroot%\System32\Wbem\Repository\*.* c:\wmibackup
DIR %systemroot%\System32\Wbem\Repository
NET start wscsvc
Net start winmgmt
Net start iphlpsvc

WAIT 10 minutes for the store to rebuild, then reboot.

wait another 10 minutes (just in case), then run another MGADiag report.

By the way, how did you acquire your Windows license? - it's an MSDN-type one, and is not for general sale.

I have been unable to install Windows updates since mid-December, and now have some 11 outstanding.

My machine is a 5 year old Acer Aspire M3910 64 bit Intel Core i3 CPU 540 @3.07GHz with 8GB RAM running Windows 7 Home Premium SP1.

I have downloaded and installed the System Update Readiness Tool from the Microsoft site. However the CBS.zip file generated from the CBS file produced by running this tool is some 12 MB in size and falls foul of the 8MB limit imposed by the forum, and I cannot attach it. How do I get over this?

I have also run SFC /SCANNOW, but it identified no issues.

Help to resolve this updating error would be very much appreciated.

Thank you in advance!

Hi All

since a few days, my PC won't install 4 windows updates:

I investigated a bit on my side, and the last sucessful update was in june this year, i have the error code 0x80073712 since the 25/09/2014 in the events journal
When I found out about the issue yesterday, i tried:
1. WindowsUpdateDiagnostic.diagcab which fixes issues, but then windows update still raises the same error code
2. after reading thread from Chuckylena i also tried the command "DISM.exe /Online /Cleanup-image /RestoreHealth" but the error below is raised (my system is in french)

All Windows automatic updates have been failing since 2015-11-12. The last successful update was the Windows Malicious Software Removal Tool x64 - November 2015 (KB890830) on 11/12/2015 03:17. The first failed update since then was Security Update for Windows 7 for x64-based Systems (KB3100213) on 11/13/2015 20:25.

Manual installation of the pending updates does not work. Reboot does not install the pending updates either. Another symptom was that Windows was no longer detecting my third party Anti-Virus software. I removed and reinstalled the software thinking it might be related and Windows started detecting the Anti-Virus software again but I can no longer access the computers from other computers on my home network. For now let's focus on the Windows problem which may be hardware failure induced--hardware crash/power cycle without a Shutdown.

System details are as follows:Dell XPS 420 Desktop
Windows 7 Home Premium 64 bit, SP1
Intel Core2 Quad CPU Q6600 2.4 GHz
8 GB of memory
nVidia GeForce 8800 GT
Generic Sound (on motherboard)
Intel RAID 1 volume with two Seagate Barracuda ST1000DM003-9YN162 1 TB SATA Hard Drives
Dell KM632 Wireless Keyboard and Mouse
McAfee Internet Security Suite

Hi y'all,

I'm having trouble with Windows Update.
Since yesterday around noon, I have not been able to install the rest of the updates that the program said needed to be installed.

I turned my computer on, and WinUp said there were 25 updates ready to be installed. I clicked Install Updates and after a few minutes it said some updates weren't installed and gave me error code 80071A91. Only 8 updates installed (most having to do with .Net stuff) and the other 17 I have had no luck installing. The updates that haven't installed are in the screen shot I attached- at least I believe it attached

Anyway, I also noticed Cumulative Security Update for Internet Explorer 10 for Windows 7 Service Pack 1 for x64-based Systems (KB2879017) was "behaving" funny. I ran WinUp with only this update to install and it said it did install it. When I restarted, and reopened WinUp the update was not on the list. I tried installing the rest of the updates, and when they failed and I clicked on View Important Update, "Cumulative Security Update for Internet Explorer 10 for Windows 7 Service Pack 1 for x64-based Systems (KB2879017)" was back.

I'm not entirely sure what to do. I have done the following to try and fix:

1. Error checked Local Disk C. Tried WinUp, no luck.
2. Defragmented, then error checked again, and ran WinUp, no luck.
3. Did the command prompt sfc /scannow. Restarted. Ran WinUp, no luck.

Please help me. I thought I took very good care of my computer. ... Read more

I've got a Win 7 pro 64 bit SP1 machine on a domain, pointing to a local WSUS server which has stopped installing updates. The update gets to the point in the progress bar where it should be installed but then returns failed with 80070643 & 80071A91 error codes. Currently there are 45 updates outstanding. All other machines on the domain receive and apply updates successfully.

If I try to apply updates 1 by 1, I get a mixture of the errors already stated depending on the update i'm applying.

I've run chkdsk & sfc /scannow.

Suddenly Windows 7 has stopped installing Windows Updates. It downloads, then creates restore point, starts installation, but then comes back with the error code 800F0900. This happens with all the updates when carried out individually, critical or optional. I first went through the process of clearing all the Start-up Programs in the Services section of msconfig. As that did not solve it I then stopped all but MS services, and that did not solve it.  I tried the Microsoft .NET Setup Verification Tool. This said there were problems that it could not fix and sent a report to Microsoft.  Following an earlier thread on this site, I installed and used the Windows Repair program from Tweeking.com. This failed to solve the problem. Does any one have any other possible advice to help solve this problem ?

I have been having some recurring problems with the attempts to install some automatic windows updates.

Security Update for Microsoft Office Acess 2007
Security Update for Microsoft Office Outlook Junk Email Filter

I am not able to install these updates, maybe any other updates in general. After attempting the install the following install window says, "Windows Update encountered an unknown error." Next to it an error code 80070643. Microsoft provides a solution to the problem, by re-installing Microsoft NET. Framework. They also provide a link to the program NET. Framework cleanup tool that enables you to uninstall NET. Framework, and it's components.

I followed Microsoft's instructions to solve the issue, though I've been put at a standstill. I have used the NET. Framework Cleanup tool to uninstall NET. Framework and it's components (states that it uninstalls all versions, 1.1 SP1 1.1, 2.0, 3.0, 3.5.) Then afterwards instructed to reinstall NET. Framework, specifically in an order, 3.5 then, 1.1, then 1.1 SP1. I start with 3.5, then as the installation starts it says that to contiunue installation I must turn off or on windows features in the Control Panel. I do so and turn off all Windows features. Then continue and it again states to turn off features in the Control Panel.

I wasn't able to continue the process, and I am also concerned that this is the same error that made me unable to install Microsoft Security Essentials, (as t... Read more

I just got a new Dell Inspirion laptop with Windows 7 Home Premium Service pack 2. As usual there were several Windows Security updates that needed to be installed. Took two days to install them all. Or I thought all had installed. But after Secunia PSI kept insisting that no updates were installed, I checked the update history and found several had failed to install. All have the same Error code of 800F0902
I ran Microsoft Fixit tool, which said it detected no problems. But obviously that too failed.
The list of updates that failed are too numerous to report but here a few:
Most seemed to have to do with the Net Framework 3.5.1.
Does anyone have a clue how I can resolves this? Most importantly is my new Dell a lemon?

Hi all

I am new to the forum. Nice to meet you all

I need to some help that I have put off since last month due to personal life stuff outside of Windows 7. I notice windows update is failing bad installing three updates. Two of those was last month and one very new update a few days ago.

I read the rules about posting and one things it mentions in the post was to post up the CBS log file buts it over 1gb and it wont open it even when zipped. I did ran sfc last month but it didnt pick up anything. Enabling and disabling windows updated trigger anything to work. I havent uninstalled SP1 yet but how safe is this?

My OS is: Windows 7 pro SP1 64bit.

The three updates are:

Security Update for Windows 7 for x64-based Systems (KB3126587)

Security Update for Windows 7 for x64-based Systems (KB3126593)

Security Update for Windows 7 for x64-based Systems (KB3140410)

And they all have the same error code: 80073701. I did find a standalone installer for KB3126587 but the error message I keep getting when I run it is: "The update is not applicable to your system". Even though it damn well is the correct version.
Any directions on where to go from here? I feel like I have run out of options

G'day guys. As the title says I've been getting an 80073712 error while trying to install some updates.

Additional info:

These files have been turning up in my external hard drive while I try to do the updates. At first I didn't know what they were but after some searching it turned out that they were just where the downloaded updates were stored. May or may not be relevant. Tried doing an update with the hard drive unplugged through the System and Security/Windows Update interface and it still failed.

I also tried to download and install the KB3068708 important update manually from the microsoft website but when I tried to install it it said something along the lines of "Update not applicable to your computer".

I am having an issue installing Windows Updates (WU) all have Error Code: 80070005.

Nine updates installed after several tries, but there are about 50 updates waiting to be downloaded and installed.

I ran the SURT, but it kept spinning...all day, so I canceled it. Tried running it again, but it wouldn't let me run it again.

I ran the SFC Scan and have the SFC detail log attached. Appears a lot of files were repaired and some could not be repaired. The files that couldn't be repaired are mostly sample MS music, pictures, etc. Stuff I am not interested in.

Maybe one of my cleaners deleted same as a useless/unused file or maybe a virus corrupted some files? I didn't see anything in the SFC detail log pertaining to WU?

The CBS compressed zip log is 13.6MB, which is over the 8MB upload limit, so couldn't upload it?

On June 23, 2016, MSSE picked up a Rogue: JS/FakeCall.D labeled (Severe). It was quarantined by MSSE, I deleted it.

Malwarebytes this past week picked up and quarantined a few rootkits labeled as severe or a threat. I deleted those. Not sure if these items affected WU or not?

Would the Windows Update - Reset tutorial would work to fix my WU issue here? Seems like a uncomplicated fix?

So any help here would be appreciated, Thanks!

Most system security experts would advise a complete RE-install of any OS compromised by a Rootkit, but you, from your own admission, have had few.
Iam NOT a security expert but in this case I WOULD, if you can identify them, look them up at BleepingComputers they have an excellent catalogue of Rootkits and there impact/removal.
Just removing them does NOT allways guarentee a clean system.

Having said that SFC has done a pretty good job of repairing some of whats been infected/changed, but it is advised to run it 3x.
From what i can see there are certainly still some errors, in Windows media player, and there are likely to be others
SURT can take >>hours<< to run especially on a previously infected system, as it also makes repairs as it goes along

You can run the troublshooter, if you want.

I posted this yesterday, but as this was my first post in the Windows 7 forum, I was instructed that I did not include all of the required information. I closed the old post and am re-posting with all of the required documentation.

For the past 2-3 months I've been receiving the same error in Windows Update every time I try and update: Error 80246008. I've tried the Microsoft Fix It application and the same problem occurs. I took a look into the services and when I try to start one service required by Windows Update it always fails because its core services are not launched, so I tried to launch those and those won't even launch. How can I go about fixing this?

Hello there,

For the best part of a year I have been struggling with the exact same issue. I am unable to install these 2 pending updates. Consequently, I am unable to update further and am stuck on an old version of Windows 10 exposed to several threats.

I have already contacted Microsoft support several times and their outcome every time was to "purchase higher support". Prior to this post I have reinstalled Windows many times freshly and I am unable to solve this issue.

The only interferences I can think of is the fact I have changed the default program installation folders in the registry to a seperate drive (P:/ Drive) and my user is saved on a seperate drive (S:/ Drive).

The error I get is as follows:

? Cumulative Update for Windows 10 Version 1511 for x64-based Systems (KB3176493) - Error 0x80070bc9
? Security Update for Windows 10 Version 1511 for x64-based Systems (KB3172729) - Error 0x80070bc9

Any help will be GREATLY appreciated as I am getting to the ends of what I can handle.

Many regards,

This is frustrating ! Windows Update will not update any number of updates, giving me errors 80070643 and 80071A91.

I've tried running -

the Windows Update troubleshooter
the Windows .NET Framework hotfix
the Microsoft Office 2003 hotfix
the System Update Readiness Tool - hotfix KB947821

I've also updated .NET Framework to 4.5, just to be sure.

Still failing updates. Anybody got any ideas?

I have several updates(currently 3 but it was 5 last time I tried) that fail.
They seem to download alright, but on installation the progress bar takes a few leaps
to the end, and it's all fails. I stopped updating for a week or so, and today, I was able
to successfully apply 14 out of the 17 updates that were available. So now it's just these
3 for some reason.

Those are:

Important updates
Update for Windows 7 for x64-based System(KB3040272)
Update for Windows 7 for x64-based System(KB3065979)
Update for Windows 7 for x64-based System(KB3064209)

Here's the info:
OS is Windows 7 Home premium(64bit)
The error code I am given is: 8024200D
I have downloaded and run the SURT tool.
I have also several times run the sfc /scannow cmd.
I repeatedly tried to update at every stage, with no luck.
The CBS.zip is attached.

Running the automatic troubleshooter from the microsoft site reports the following
as a Windows update error and says it couldn't fix it:

InformationalError Report
RootCause: RC_DataStore
ErrorCode: 0x800F081F

As you can see, the error code there is a different one than the one I get directly from
the failed Windows update.

Any help/suggestions much appreciated.

I searched for the updates in question online, and downloaded and installed them manually. I then checked for new updates(after a reboot), and windows update successfully downloaded and installed all by itself. It seems my troubles are a thing of yesterday. Hooray! Still though, I don't get why this happened in the first place ... oh well.

Good Afternoon,

I have spent this afternoon reading the other posts and following the Windows Update Posting Instructions thread so hopefully I've gathered has much info as I can.

Since 10/07/2014 I am having serious problems with 9 updates in Windows Update.
I just took a look at some other topics in this forum section and it seems I am not the only one having these problems.

I've already tried several things i've found on the internet, but nothing really nothing worked out for me.
I've tried the hotfix, didn't work out; i've tried multiple CMD commands, didn't work out; i've tried to rename the catroot2 folder, didn't work out either...

Is this problem common? Because most of the updates are important; so i'd like them to be installed and they keep on failing every day since then.

If I need to post or upload something, please tell me, because i'm not a computer expert ;-)

Hey all,

So I am currently reinstalling Windows on my dad's old laptop after the hard drive decided up die on us, and I stumbled on a problem that's a bit too hard for me to fix.

Namely, I am completely unable to install any Windows Update. Not even MSE will install.

I tried running SURT, but got error code 0x8000247
I also tried running SFC /SCANNOW, it ran the verification fase until 98% and then stated that there where unfixable problems.

The displayed error codes are:
In WU: "8024A000"
In SURT: "0x8000247"
Whilst installing MSE: "0x80070643".

Attached you will find CBS.log and MSINFO with my system specs.

For almost a year I haven't been able to download a single update for Windows 7 (Have around 75 pending important updates to download). Sometime ago, I recall stumbling across a backdoor virus on my PC. It prevented me from accessing any of my programs, including the internet. I had to go into safe mode to remove the virus. A few days later I had pending operating system updates. When I went to update, it was unable to even gain access online (my internet connection was fine). Microsoft Security Essentials also, was compromised and unable to update itself. I was able to correct it, though Windows Update has remained the same.

I have attempted to clean-boot up Windows, in hopes that it had been Malware Bytes that was blocking the updates all along. The Updater was able to find out that I had 75 pending updates, though when it went to actually download them, it was unable to and gave me an error code, 80246008. I have seen another post from a user here that had a similar problem, but I'm not sure him and I have the exact issue. (Windows 7 cannot check for updates & error 0x80070002)

I've had problems with Windows XP, 7 before. But nothing this frustrating or difficult to figure out. Any help you can give me would greatly be appreciated.

For a week now, I have been calling all around Denver, trying to fix this problem. I have read the help that I can find, but unless you are a really high level techie, it is difficult to understand. When I click on the Vista button asking if I want to search for updates, I get a dialogue box that says I need to install new software in order to update. Windows Updater will close and reopen. Every time I do that, I end up with the error message found in the title of this thread. I tried removing my AVG Anti-Virus software and then tried to update. One piece of advice said to try this. It made no difference. Whatever I do, I am always unable to update, at least in the last two weeks. It was working until the last update I installed. I believe that was on September 28th. Any ideas you have would be greatly appreciated.

A:Code C015001A-Windows Cannot Install Updates

Found the following on microsoft.com-

Subject: RE: windows vista update error code c015001a 8/24/2007 10:30 AM PST

By: fruman44 In: microsoft.public.windowsupdate
Well, I fixed my problem. This has been frustrating, I'm glad its working
now! In short, here's what I did:

1. Formatted my Windows partition.
2. Reinstalled to this partition.
3. Logged in as a user, and then rebooted several times without doing
anything else, to ensure that all the Windows system and temp files are
created properly (rather than logging into an account and having it created
the user folders/files right then).
4. Right clicked on Windows Update --> Ran as Administrator (even though
my account was already an administrator).

It worked!

I think that perhaps in earlier attempts I had several other processes
running and the computer would lock up, so I would have to do a HARD reboot.
I bet there must be a Windows Update that fixes some driver problem,
instability problem with my installation (which has hence been installed,
Doing the HARD reboot would not cleanly unmount the filesystem, and I think
Windows Update must like a clean filesystem (even though chkdsk would never
run upon the next reboot, making me think that all was okay...). Having an
unclean filesystem might cause Windows Update into loop somehow.

Anyway, try the steps above, I bet they will work for you too.

I have about 15 laptops running Windows 7 Pro SP1 (brand new, just out of the box).  I've been able to install quite a few updates on about 3 of them (just started working on them).  However, now, I'm getting error code 80200011 when I attempt
to install additional "required" updates. 
I've tried clearing the BITS queue, deleting softwaredistribution folder and ran SFC and nothing came up as being an issue.  I've searched the net on this issue, but there doesn't appear to be much on this specific problem.  These systems
are behind a proxy server.  I have other (XP, Windows 2003) systems that are able to update, but is there an issue between WIn 7 and some proxy servers?  If so, why would I be able to install some updates?
Any help or suggestions would be GREATLY appreciated. Thanks all.

A:Windows 7 Pro - Windows Updates Error Code: Code 80200011

Chek that your proxy is configured correctly, and if you can follow these steps to resolve this issue : stop the Windows Update service and make sure that the "Backround Intelligent Transfer Service" and "Cryptographic service" are started and then go to
C:\Windows and rename the software distribution folder to UpdateOLD , and finally restart the Windows Update Service

I suspect that your WU problems will have to wait, until your BSOD problems are solved - but I'll take a look and see if there's anything that relates which may be causing your BSODs and see if we can fix that.

Edit - now I've got the logs downloaded!
There's no significant errors in the CBS.log background - and both SFC and CheckSUR are clear.
I', not sure I can do anything that'll help your BSOD problems, and I think WU should wait until that's cured.

Windows Update fails to install any updates, and shows error codes 80070643 and 80071A91.
There are several threads about these errors, and I have read all of them.
I tried the Microsoft fixits 50123 and 50709.
I cleaned out .NET framework, and did cleanup
I tried Dockster's fix here www.sevenforums.com/windows-updates-activation/97775
I tried the "Set autoreset true" fix.

and then, after all that, I finally fixed it with...Checkdisk!

(My computer / local disk C: / right-click / properties / tools / check now / "Yes" to scheduled check)

I hope that by putting this all in one place, I can save someone a bit of trouble.

You should probably also run an SFC to be on the safe side - in an Elevated Command Prompt window, type

This is a Toshiba Satellite C650 laptop that has had a history of issues with updates.  Last year some updates began to fail and we could not get them to apply successfully.  Other issues occurred, bsod without warning, etc.  Finally in Nov/December I did the factory reset and then re-applied all of the updates successfully.  Things seemed to be working ok after that.  After a month or so the laptop was then out of the country and offline for around 4 months.  Shortly after coming back online it began to have issues with some updates, until now when it will not even successfully check for new updates.  Also occasionally blue screens again.  Also, if you select View update history, it says "you have not tried to install any updates for your computer"
We use ESET Nod32 antivirus and it hasn't reported any virus/malware issues.

-Running Windows 7 Ultimate 64bit Service Pack 1

Hello there, I've just built a new computer and am having trouble installing Windows updates on my fresh install.

When I go to Windows Update, I get the following message:

Install new Windows Update software

To check for updates, you must first install an update for Windows Update. Your automatic updating settings will not change

To install the update, Windows update will automatically close and re-open.

When I click 'Install now', the window disappears and I am then confronted with the following message:

Windows could not search for new updates

An error occurred while checking for new updates for your computer.

Error(s) found:
Code 800F081F Windows Update encountered an unknown error.

Does anyone know how I can get updates to work? Is there some way that I can manually download and install this update for Windows Update?

Thank you.

A:Unable to install updates on fresh Windows 7 SP1 install

I'm guessing that your installation media already contained SP1, is that correct? Since this is a clean install my first thought is something happened during the installation process to damage or corrupt some system files. I'd try the Microsoft troubleshooter first.

Troubleshoot problems with installing updates - WindowsUpdate_dt000

If that doesn't work I'd try running the System Update Readiness Tool.

What is the System Update Readiness Tool?

If still no joy, and only because this is a very recent clean install, I'd just reinstall Windows 7 again. If the problem persists I'd start looking into the possibility of a bad installation disk, hardware issues, etc. Please post back if any of this helps or not.
