How to fix the issue
Even though Microsoft hasn’t yet acknowledged this problem, a solution from Quick Heal confirmed by multiple users (1, 2, 3) says that the following steps can be used to fix the error so that you can turn off your Windows 7 device again (only works for users of Professional, Ultimate, or Enterprise versions):
- Open the Run dialog by hitting the Windows+R combo, type gpedit.msc and hit OK.
- Go to Computer Settings > Windows Settings > Security Settings > Local Policies > Security Options
- Search User Account Control: Run all administrators in Admin approval and set it to ENABLE
- Open Run again and do a gpupdate /force
- Restart the system by opening the Run dialog again, type shutdown -r and hit OK
If you can’t turn off after the gpupdate, then kill and rerun Explorer.exe from the Run dialog.
