Thank you. Please follow these steps to undo the changes made by Windows Update.
Start or restart your computer so that you are at the login screen (but don't log in just yet)
Hold down (and keep holding) the Shift key. Click the Power icon in the lower right corner and select Restart.
Release the Shift key when you see "Please Wait"
At the Choose an Option screen select: Troubleshoot>Advanced Options>System Restore
Select your account and enter password ***** prompted.
When System Restore starts, click Next.
Put a checkmark in the box labeled Show more Restore Points and select a restore date just prior to the updates yesterday.
Click Next and finish.
When the restore has completed and the computer restarted log in and the issue should be resolved.
-when that has finished Windows Update settings will need to be changed so that Microsoft does not try to reinstall the updates in the future.
