Please update this KB with cautions! After updates, my system won't open Edge and Start button won't work or with very slow response!!!

Good old MS, I've never trusted the 'updates'!!! Maybe leave your PC idle for a couple hours. I think there were net framework updates included which can prompt heavy background task action - once it finishes doing its thing perhaps your PC will pick up. Although it doesn't seem super promising because mine seems ok. If after that still no improvement do you have a system restore point you can roll back to?

This new update changes my Date format to yyyy.mm.dd


I had to manually change it back to mm/dd/yyyy

Update installed. No problems so far. The update didn't change my date format. It's still mm/dd/yyyy

Two desktops with 1511 Pro and one Laptop with 1511. All updated and it all looks good.
