Disk usage 100%

Bump...this didn't work for me either.  This is still an issue for me and I'm sure many others.  I've tried superfetch virtual memory adjustment, removed 3rd party virus protection, task scheduler, etc...  What next???  This laptop is nearly unusable due to this issue!

With a Win10 PC, you're almost always going to experience a very slow PC at times because Windows Update (WU) is hogging your PC, searching for, downloading, and installing updates -- to bring your PC up to the most current version of Windows.

And, when it does that, it can force the disk usage to 100% -- and keep it pinned there for some time.

Some folks have been told that resetting your PC will fix this. but, if you reset your PC, you only make matters WORSE! Why? Because you will reset Win10 back to the original version that came preloaded on the PC and that will restart Windows Update all over again.

To find out what version and build of Win10 your PC is running, do the following:
1) enter "cmd" (without the quotes) into the search area and select the Command Prompt option
2) enter "winver" into the command window (again, without the quotes)
3) the most current Win10 is v1809 Build 17763.316

If yours is older than that, most likely WU is hogging your PC trying to update it.

To disable WU temporarily, do the following:
1) Enter "services" in the search area (again, without the quotes)
2) When the window opens, scroll down until you see Windows Update
3) If it say Running under status, that indicates that WU is running
4) To change that, double-click on that task, select Stop under the Service status, and then Apply
5) That should stop WU -- and you should see an immediate improvement in performance

WU will restart itself automatically later on, so you basically have no choice than to bear with it until it finishes.

Thanks for the advice, but unfortunately it didn't fix the issue.  Still getting 100% disk with the latest updates and the WU disabled.  What should I try next?

Thanks in advance!

OK, so clearly SOMETHING is hogging your disk and you need to find out what it is.

So, run Task Manager and start cancelling the running tasks -- until you see the disk usage drop.
