Windows update error code 490

Q: Windows update error code 490

Hi I was wondering if anyone knows how to fix this windows update problem. The windows update window says Error code 490, I am also receiving error 800736B3 as noted below

Any help someone can lend is greatly appreciated


Preferred Solution: Windows update error code 490

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: Windows update error code 490

after successfully getting that update to install which I didn't think was the entire service pack, I rebooted and another update pops up for Win 7 SP1 and that one throws another error. 800736B3

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.
Cheers and many thanks in advance,

CBS.log MSINFO32.nfo

That's very reminiscent of similar errors in Win7 - and I wouldn't be surprised to see it being non-genuine.
Please post an MGADiag report BEFORE doing the below potential fixes.

This may simply be caused by a bad set of Intel Storage Matrix Technology drivers -

Installing the Intel Drivers
try downloading and installing them from here -


Once complete, please reboot twice, then post another MGADiag report.

If nothing has changed, try this...

Please run the following commands in an Elevated Command Prompt


once complete, leave the system alone for at least an hour to rebuild the database, then reboot, and run another MGADiag report and post the results.

If neither of them work, we'll re-evaluate.

I recieve error C80003FA whenever I do a Windows Update run. It doesn't get past the stage of checking for updates.

I've tried several fixes including:
- Waiting 15 minutes and running Windows Update again.
- Letting Windows Update run on its own schedule.
- SFC /Scannow
- Renaming the Catroot2 Folder.
- Running 3 different Fixit tools.
- Clean windows install.

After each and every one of those fixes I've tried windows update and I still get error C80003FA.

SFC Scannow has previously said no errors, but the last run through it said there were unfixable errors. I've got the log, though for brevity's sake I will keep it until someone asks for it.

Any ideas?

First, excuse my english, I'm trying my best.

I get error C80003FA whenever I do a Windows Update run.

I did the Windows Update Posting instructions. When I did the SURT installation, it didn't finish and I had to reboot the PC. Then it work.

I've tried sfc /scannow several times before with different results: sometimes finished with no errors, sometimes finish with unfixable errors and sometimes didn't finish at all.

I uploaded the CBS.zip

Hope you can help me, thanks.

My Windows Update has been failing to update for a while now and I can't seem to find the solution. Here's the run-down of what happens step by step:Launch an update scan for Windows Update

I didn't see any posts about this, so I hope I am not double posting.

After removing a drive load of viruses, I am still not able to update Windows Vista to Service Pack 1. I have even tried to create a new admin user account in hopes that this would work, but no go. I tried running sfc.exe / scannow from the CMD and it did report that it was unable to repair wextract.exe. Also, the file reportingevents.txt located in %system root%\windows\softwaredistribution\reportingevents.txt lists "Windows Update Client failed to detect with error 0x80070490".
Although, I think Windows Defender can update. I need to take a break.

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.

For more than one year, my automatic Windows Update process has unsuccessfully tried to install (around once a day !) KB3001652 (Visual studio 2010 Tools for Office Runtime). I haven't seen any problem with other automated Updates of Windows, MS Office, NET.Framework, etc....

I have tried first "Fix-It" which doesn't produce any error message. Secondly I launched "SURT", which tells me "This update doesn't apply to your computer". "SFC /scannow" doen't report any violation issue.I don't know how to do for resolving this problem.

I'm using Windows 7 Professional 64 bits SP1. Norton (NIS, the most recent version), "ShellfolderFix" and also Tune-Up utilities are installed on my PC. I have also tried to install KB3001652 manually after having deactivated the firewall and the "Auto-Protect" functions of Norton : no success.

Fellow code crunchers,

Every once and a while I will have a download waiting from HP in Windows update. I will try and download it, but it always fails. I have a HP Laser Jet 600 M601 and I believe that's what the download states it is for. Below is the error message I keep getting every time I try and download it.

I am not too distressed about this, but I am curious to know what is happening.

Thanks for your answer in advance.


A:error code from windows update

Error details: Code 800F020B. This apparently indicates that the device does not exist. So the update may not be applicable to your printer.

If you are not distressed about it & your printer is working well, it might be best to just hide the update, so you don't keep getting the update, & forget about it.

If you really want the update it's always best to get updates directly from the manufacturer, so go to their website & check for any updates that are applicable to particular model printer.

Hello all I am scouring the internet for answers but I can't seem to find any so I thought I should ask the Gurus down at the Windows Vista Forums. Anyways I am trying to install the Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update (KB951847) x86 and all I get is this error. Does anyone know how I can fix this?

A:Windows Update Error Code 643

Hello Peacemaker,

When you try to install an update for the .NET Framework 1.0, 1.1, 2.0, 3.0, or 3.5, you may receive Windows Update error code "0x643" or Windows Installer error code "1603"


To successfully install the update, uninstall all the versions of the .NET Framework on the computer, and then reinstall all the versions of the .NET Framework on the computer. You may have to work through more than one of the following methods.

Method 1: Manually remove and reinstall .NET Framework
To manually remove and reinstall the .NET Framework, follow these steps:

1. Remove the .NET Framework.
1. Click Start, and then click Control Panel.
2. Double-click Add or Remove Programs.
3. Note each version of the .NET Framework that is already installed on the computer. Then, uninstall all the versions of the .NET Framework.
4. When you are prompted, restart the computer.
Method 2. Use the Windows Installer CleanUp Utility to clean up the MSI database state for all the versions of the .NET Framework.

1. Download the Windows Installer CleanUp Utility. The following file is available for download from the Microsoft Download Center: http://download.microsoft.com/download/e/9/d/e9d80355-7ab4-45b8-80e8-983a48d5e1bd/msicuu2.exe

Hi -

The first thing I would suggest that you try is removing PC-cillin Internet Security as its firewall can interfere with Windows Updates.

Trend Micro removal --> http://esupport.trendmicro.com/1/How...n-my-comp.aspx

Reboot upon completion.

Install MSE --> http://www.microsoft.com/security_essentials/

Try Windows Updates --> www.update.microsoft.com

Hi -
I'm not getting Windows Update to run. HP p6240f, Windows 7, 64-bit OS
When I go to shutdown, the shutdown button has an orange shield that indicates it wants to update.
If I go to Windows Update and and say "Check for Updates", it tells me to Install new Windows Update software. I press Install Now and get "windows could not search for new updates. Error found Code 8024DFFE Windows Update encountered an unknown error". When I press "Get Help with this error", I select Windows Update Troubleshooter, which opens a Diagnostics Troubleshooting Wizard, which opens "Window Update, find and fix problems with Windows Update", which runs a repeating cycle of Detecting problems, collecting files, checking registry, Resolving problems .... over and over until it finishes eventually saying that it was not able to fix all the problems. In particular is a new "Windows Update error 0x80070490(2014-08-29-T-09_02_42P)". I attach the picture. I've done this a bunch of times, including rebooting to see if that matters.

This happened a week ago and the same thing happened as in the preceding paragraph, except that afterward - even though it gave all the same error codes - the Windows Update successfully ran.

I found a suggestion on a MS Windows site to run (in an administrator's Dos window) sfc /SCANNOW, which takes a long time to run and I did so and it found nothing and still the problem exists.

I found a note from a Go... Read more

A:Windows 7 Update Error, Error Code 8024DFFE

Hi. Firstly, thanks for the info. I had encountered the same problem with windows update error 8024DFFE on my Acer 4830, Win7 64bit 2 days ago and was trying to find a solution online without any success. But then I came across ur post and realized that I have a similar configuration as you. I also uses comodo firewall and avast antivirus. This led me to think that either one of them is the problem. I disable the firewall and can now check for updates. How that helps.

I have had this error for a few weeks and haven't managed to get rid of it. I ran System update readiness tool and Fixit, as well as the Hotfix B947821-v35-x86. Previously Windows update would say it was unable to search for updates, but after a few fixes it began to admit itself needed updating. However trying to do that produces the same error.

Here is the Checksur log, giving these corrupt files:

You neglected to mention that this system is running Vista SP2, rather than Windows 7!

In this case, it doesn't matter too much as all the files involved are the same.

I'll post a fix protocol when I can get through the backlog

For last month have been unable to install updates to Windows Vista. All updates now result in error 8007010B
(a while ago I did get a 'blue screen' error but it disappeared before I could make a note of it)

From link within 'Windows Update'
Ran Automatically diagnose and fix common problems with Windows Update Fixit from MS help and Support.
Issues found: Windows Update components must be repaired. .. . . . . Fixed
Tried one of the oldest updates - failed 8007010B.

Tried Microsoft Answers


Method 1
System Update Readiness Tool does not list KB947821

Method 2
System File Checker tool ends with message
'Beginning verification phase of system scan.'
'Windows Resource Protection could not perform the requested operation' *****????

Assuming I have no corrupted system files continued to step 2

ran msconfig and restart as clean boot

Reboot (ZoneAlarm virus software started)
Tried to install oldest update - failed 8007010B
ended ZoneAlarm
Tried to install oldest update - failed 8007010B

Tried running System file Checker (sfc /scannow) - same result as above

A:Windows update - error code 8007010B

I'll tell you that registry cleaners aren't recommended around here simply because they can harm your computer by cleaning the wrong thing if you don't know what you are doing. I'd stay away from them if I were you. I can't be sure about this, but I'll tell you that ZoneAlarm's reputation's gone down in the past few months. Some of the things they've done are appalling. And one thing to check is the error you got regarding Windows Resource Protection. WRP is the mechanism Windows uses to protect its crucial files so that users cannot touch them. I don't think WUA uses WRP at all, but I'll look into it for you. And another thing to check for is to ensure that you are connected to the internet when you check for updates. If not, then you'll get an error for WUA's lack of access to the Microsoft site will cause downloads to fail.
