Windows 10 May 2020 update is now available

It will not allow me to clear the temporary files it closes the Settings tab but if I reopen then the temp files are still there.

I want to unsubscribe. I see no option. Can someone help?

Clean your device by selecting "Start" "Settings" "System" and then "Storage"

Which puts us here:

Now select the trash can icon "Temporary Files" under Windows (C) and once it finishes enumerating all the junk there check the boxes next to ALL of them and select "Remove Files" at the upper left of your screen:

You can then reboot. Let us know if you have any further issues.

I update and now I can't use my xbox one controller,  I even think that it doesn't work anymore

Actually,. I did not force the update..

When I went to my Check for Updates this appeared below: Feature Update for Windows 10, version 2004 - The next version of Windows is available with new features and security improvements. When you are ready, ready for the update, select 'Download and Install."

This came after several weeks when I checked for updates getting notices from Microsoft saying my computer was not ready for the update, and would tell me when my system was ready for the update.

I assumed that when that previous notice - which Microsoft sent out to users who regularly checked for updates to tell them to wait and would be told their systems were now safe to get the update after ensuring the systems had the right updates, drivers etc. - that it was safe to install. And I regularly check to make sure my system has all the newest security updates, patches etc.

Now that I rolled back to the previous build, 1909, I'm still getting the notice on my Check for Update that my system is ready for the new May 2020 update when it is obvious there are still some bugs to be worked out.

I'm just trying to find out what that bug might be as it was caused by the crashing of Outlook. Before that the update was working fine, and I was quite pleased by the results, the improvements to the system etc.
