working OK on the rigs I've updates

 
No worries here.
 

Looks like Windows 20H2 has broken P67/Z77 boards. I've tested a few, all possible combinations and they wil always BSOD randomly, after some Google research it turns out it's a more widespread issue.
SATA SMART errors are going absolutely crazy every second.

Yep something is broke. My friends HP desktop is in a twilight zone kind of refresh loop where her MS account is broken along with OneDrive error messages. When we fix them it won’t save them after signing out or rebooting. On top of that, HP bios settings suck!

All good here. 

Is it just me, or does Microsoft seem to be getting a lot more lax in their patch quality control?  I've been reading about the past few months of patches and the problems they have presented, such as blue screens when trying to print, or lower fps in games until the patch is uninstalled.

*No problems so far. I do now have in the taskbar the current temperature, and it say's it's sunny. This wasn't there before the updates.*

No problems with this weeks round of updates.
