Windows 7: Windows update runs for ever.Also svchost consume 50% of cpu

It appears that the DLL errors that you got are not a problem. Those errors should not show up when using the batch file from the tutorial...since the DLL registration commands in that batch file use the "/S" switch to silence such errors (hide them from the user). The errors might appear when using the MS Fixit tool.


Many months back, the Windows update process changed. Lots of people were seeing long search times (20+ hrs) to get a list of updates to be applied. Also, RAM and CPU usage was high. I have a Virtual Machine (VM) running W7 pro 64bit with only SP1 installed. I have brought that VM up to date with all patches many times. When I exit the VM, I have it set to revert to the unpatched state. In the past, the long list of about 200 updates could be created within an hour. Then something changed and that list took much longer to create.

I found that if I manually installed this update...

Installing and searching for updates is slow and high CPU usage occurs in Windows 7 and Windows Server 2008 R2
...the time that it took to build the list of about 200 updates only took about 10 minutes. This was a bit puzzling to me because since the issues that the KB supposedly fixed do not exist in that VM:

SCCM nor W10 was installed in that VM.

KB3102810 has been replaced by later versions of the Windows Update Client. My testing of each replacement seems to indicate that they include the fix for the long search time too (as expected).

There must be other reasons why the Windows Update process can take so long and consume so much RAM & CPU - since updating to the latest version of the Windows Update Client is not correcting these issues for every user. You might want to see if MS's support staff will fix this issue for you. I'm not sure what else to try.

So ,

it seems that everything is ok now.

The pc managed to locate all windows updates (41) and right now they r being installed.

I do not know how much time it needed because i let it overnight while i used to let it search for updates 15 minutes max.

I would like to thank much UsernameIssues for his excellent technical advisory and HelloItsMeAgain for his resolution suggestion.

Hope this thread will help others too.

P.S. In the morning the windows update was there suggesting me to install windows 10. I think that i had seen once more this screen again before through all this process but i closed the window.This time (probably because i had just woke up) i noticed the small letters link below that windows 10 suggestion, which revealed me the windows 7 updates.

You are welcome.

If you were offered W10, then you might have the W10 installation files on your computer (~3GB to 6GB). If you want W10, then keep those files. If you don't plan on installing W10, then check out this tool.

Windows update broken, svchost at max CPU
My Windows 7 update is just broken somehow. Whenever I try to manually update, I always end up with a svchost with 50% cpu usage (i.e., one core maxed out) and nothing ever finishes. It just sits there saying "Checking for updates". I've tried a number of solutions on the web - manual...

Hi Everyone, My Win 7 Home laptop was working fine a couple days ago. Didn't do anything different, didn't download or install anything. Last night I noticed the fan was running constantly and saw one of the svchosts (the one for windows updates, forgot the name) was consistently at 70%...

High Memory usage in svchost with Windows Update
Hello all, I just noticed something and wanted to be sure or see if this is normal. When Windows Update checks for updates, svchost will jump up to ~500MB in usage, or after updates have been installed. It will stay there. If just checking for updates, but I don't install any, it will drop down to...
