Windows 10: windows update stuck at 'downloading 0%'.

It is stuck on cumulative update for windows 21H1, KB5006670. I did not approve nor had any prior notice of this update. Why is it automatically being installed and why has the downloading stopped at 0%? I don't believe this update is intended for my computer. How to fix this issue on a desktop, windows 10, v. 21h2, build 19043.1266.For 2 days this computer is loading extremely slowly....can this be because of the update issue?I never see any notification if an update is in progress.
