Still over 100% CPU Usage . . . HELP

Hmm - I thought this had worked for me, and I successfully upgraded to Win 11 Pro 24H2 using the instructions above, and initially all was well. The fans weren't going crazy, and CPU usage was low/normal. However, after a reboot or two it also installed the July Cumulative updates - and once again the fans started going again and haven't stopped since.

So the answer seems to be, upgrade to 24H2, and while doing so make damn sure to pause all updates - as once the July cumulative update installs, these chips seem to have a problem.

 

Letting it just sit for awhile seems to have done the trick. CPU usage back to normal, temps back to normal, fan speed to zero. (24H2 Win 11 ARM, with all cumulative updates installed, M3 Pro & latest parallels)

 

Thanks for sharing this solution. Worked for me. Seems that some of the recent updates of windows 23H2 have messed things up.

 

Thank you for the info, I just started up my Parallels, saw it updating, hit the pause updates. Will let it sit after doing updates, thank you.

 

Rebooting and will let it run. lol. My poor MBA is going to be baking for awhile I assume.

 

Only for about 7 mins! Not bad! Back to work I guess. Thank you for your help!
