    This worked for me. Other solutions I tried, including other Power Shell suggestions did not. If you use this, give it time, It will run for several minutes. You will know it is finished when you are presented with the command line prompt C:\WINDOWS\system32>

    Windows 11 step 3 get significant number of errors that include both

    "because this package depends on a framework that could not be found.

    and

    "could not be installed because resources it modifies are currently in use"

    Windows security and microsoft store both fail to run

    I had this same problem. Admin account and standard account on the PC - logged in as standard user, running powershell as admin. The above instructions did not work. No change.

    I turned my standard user account into an admin (computer management, users & groups, users, user account's properties, "member of" tab, added Administrators). Restarted and reran the above instructions while logged in as that user who is now an admin. That worked.

    I haven't removed the user from the admin group yet, but I'm hoping the fix will continue to work.
