Windows insider preview 22621.1 (ni_release)

mhendric Nevermind.  I figured out what worked for me. I was getting access errors when I tried to delete/alter the files, in question.  Reminder for who needs it: 1.) Make sure your login is in the local admins group. 2.) On the folder (files) in question, Right-click -Properties-Security-Advanced. 3.) Change Owner from SYSTEM to your Account (next, next, Finish). 4.) If not still open...Right-click - Properties - Security - Edit - Add your account - and give Full rights (next, next, Finish)..   That SHOULD give you the ability to delete the offending folder - and Retry the Update.   Anyway - I hope this helps someone - it worked for me!  Thanks again, Ethan!
