Right off the bat a Win11 VM had problems with the update -- during the restart it posted a message that something didn't work correctly & it was trying again. That 2nd attempt worked, but haven't come across that before. Next, when my mini-PC restarted, it didn't -- instead of restarting it just sat there with no input to the monitor. Starting it after a hard off [holding the power button down] it finished the update OK. Again, nothing I've seen before. So please be careful -- this might be another problematic update.
