and everything is super-slow. Any action on the computer is a game of Click & Wait. With Background Intelligent Transfer Service and Windows Update Service set to Manual, then the computer is as fast and as responsive as expected all day after rebooting, and CPU usage stays at 0% when we're not doing anything. As soon as we launch Windows Update though, the computer is slowed down to a crawl even though Windows Update isn't doing anything, at least not according to Windows Update or Task Manager.
Once the list of updates appears you can stop the wuauserv service.
Then close and reopen Windows Update. This should release the update process and allow you to download and install the updates. Unless Microsoft has removed the updates from being downloadable.Edited by ltpdttcdft - 10/13/16 at 9:44pm
