Yesterday my HDD was busy running for 20 or more minutes. So I took a look at Resource Moniter, it show "svchost.exe(netsvcs)"is keep writing something and I wait for another 10 minutes but no luck.After reboot it not happen again. I guess this related to Windows Update (Patch Tuesday?), any suggestions?

Hi,Have you checked in Event Viewer? Is there any error message related in the event of service crashing? If the issue occurs again, please try to use Resource Monitor to suspend svchost.exe(netsvcs) and manually stop Windows Update Service, then resume svchost.exe(netsvcs) to see if it works. This would help us identify if it is related to Windows Update.Best Regards.Dale Qiao

Hi,What is the name of the failed downloading update?Please look into "Viewupdatehistory" to see the failed update and note its KB number, if there is any failed update, you canperform a System Restore to the previous time before installing updates thenmanually download the update fromMicrosoft Update Catalog.

Best Regards.Dale Qiao The failed downloading update is KB890830, Malicious Software Removal Tool.It wasdownloaded and installed successfully after reboot, so I think this case was accidental.

Hi,So the issue isn't occuring now, is it right? If the issue appears again, please respond back and let us know. Best Regards.Dale Qiao
