Windows update 100 cpu free download –

 

Perhaps this isn’t so much an issue with the patches as it is some change made to Windows Update back end systems over the weekend? I have no clue but it is very annoying. In our case the Windows Update cpu usage also started this weekend and seems to be caused by SCEP not being able to update it’s definitions.

Then start the Windows Update service again. You will see the CPU usage becoming normal again, but only for a while because new definitions will most likely cause the high CPU usage again. We are able to stop Windows Update Service and the problem stops – what is the longer term solution? What changed with SCEP getting updates?

A user named BrandonM on another thread said that manually updating SCEP helped; but the issue seems to have returned for some users over there too. I get the feeling that it might have reccured for the users who simply restarted the Windows Update Service but I am not sure.

His steps:. However, it is just a short term fix, when new AV definitions are posted and a detection cycle is triggered the WU service issues return. I can confirm. I’ve updated definitions a few hours ago and CPU was ok. I downloaded the new definitions file size was different, so I’m sure , installed, and CPU went to normal.

We’re also seeing this. I had tried all the above fixes before finding this thread, and they only resolve the CPU issue until SCEP attempts its next automatic update and the problem returns. SCEP doesn’t successfully update without manually installing a stand alone def file with the WU service stopped.

Also, as SCEP and Updates are not working anyway, disabling the Windows Update service will buy you some time, but is obviously less than ideal. We’ve confirmed that the issue goes away if you uninstall SCEP and returns if you reinstall.

I hope a better solution is on the way. I am anxious to see what others have tried. This issue was caused by a large no of definition updates that were still unexpired on the Microsoft Update servers and evaluating the supersedence between them is what caused the high CPU issue for 10s of minutes.
