Software updates.

I have a Lenovo 330S laptop that I have never liked. I replaced it with an HP Probook (much better) but still use the Lenovo occasionally for streaming. On last boot I was informed that there was an update for my Radeon (graphics) software and foolishly I went ahead.
It re-introduced a recurring issue with the Lenovo that means it won't shut down or restart - the screen blanks off but the power button stays lit and the keyboard is inoperative. You have to force quit by holding the power switch down. I turned back the driver update but it didn't help, I did find that safe mode fixed the problem but trying to isolate the start up setting or particular driver eluded me (and considerably raised my blood pressure).

I reset Win10 and, of course, that didn't help. I even tried Win10 21H2 which windows update has been pushing; nope.
I'm currently wiping the laptop completely and loading Win10 1809 which is quite old. This in itself proved more aggravating since pressing F12 at the Lenovo screen didn't start the process - another hour or so wasted. It suddenly decided to play - maybe there's a 5 microsecond time slot when you have to press F12?

This Lenovo has always been quirky (and that's being generous), I had to run sfc /scannow quite often on it because it would suddenly get slow or programs stopped working, meanwhile my original Toshiba Satellite laptop chugs along with no issues.

Edit: Well 1809 has fixed the problem, now I have to wade back through all the win10 updates
