To prevent your kids from installing programs on the boot drive, you’ve already adjusted permissions and moved folders to the D drive. Now you’re losing admin access to the C drive. You might need to reset permissions or use a different method to regain control.
Do you have backups ready for restoration? Usually it’s better to restrict admin access instead of giving them permission to reinstall anything, or apply limits so they can’t run files in downloads and other controlled items. That approach isn’t recommended for managing permissions. Have you adjusted the permissions on C:\ at all?
Click the right arrow on c>properties>security>edit>add this user to restore your access.
If Van Is Livid’s suggestion fails... Turn on the administrator account for complete authority and restore your user settings. Open cmd as an administrator and execute net user administrator /active:yes. Log out entirely from your current session and choose the newly created Adminstrator account. Follow Van’s instructions. If successful, log out of the admin account completely and sign in to your account again. Launch cmd once more and input net user administrator /active:no to deactivate the admin role.
With Windows 11, the standard local "Administrator" account is turned off by default. But the first account you set up (or one you add from an online Microsoft account) will automatically join the Administrators group. Just verify this quickly by clicking the Start button, selecting the Control Panel, then System Tools, and finally Local Users and Groups.
