I used following method (posted by Vulcan and edited by iBug) and it worked. But next day Ive got prompt to restart and update to Windows 11. I didn't have any "Stay with Windows 10" option. What to do now?

Yes, you can stop this.
Open command prompt and stop 2 services:
net stop wuauserv
net stop bits
Delete everything from inside folder C:WindowsSoftwareDistribution (there might be a lot of files and one of the services might start up again during the process. In case you can't delete something from there, just run the commands again and complete the delete)
Rename C:$WINDOWS.~BT to C:$WINDOWS.~BT.old (It's a hidden folder so make hidden visible in "Folder and Search Options")
Restart (make sure you don't click "Update and Restart")
After restart, run Windows Update again and you're back to normal. Click "Stay with Windows 10" and pay attention not to accidentally press something that triggers the Windows 11 update in the future.
