Hi carolynmorrisXD,
Thank you for posting in the Microsoft Community Forums.
You mentioned that you have never joined a workgroup, but feel that the workgroup is controlling your rights to use all your domains, and that you are unable to get back administrator and UAC privileges. Here are some suggestions to help you resolve this issue:
I. Confirm workgroup settings
Check the workgroup information:
Right-click on “This Computer” or “Computer” and select “Properties”.
In the “Computer Name, Domain and Workgroup Settings” section, check the current workgroup name.
If you have not joined any workgroups, but the workgroup name is shown here, it may be due to the system default settings or a previous action.
Change the workgroup:
If you want to change the workgroup (although this usually does not affect administrator privileges or UAC settings), you can click the “Change Settings” button and then click “Change” in the pop-up window to modify the workgroup name.
However, please note that changing the workgroup usually does not solve the problem of administrator privileges or UAC.
Restoring Administrator Privileges
Use the local administrator account:
If you have the password for the local administrator account, you can try to log in using that account and then restore or change the administrator privileges for other accounts.
Enable the built-in administrator account:
If you don't have the password of the local administrator account, you can try to enable the built-in Administrator account (usually this account is disabled by default).
How to enable it: In the login screen, hold down the Shift key while clicking the “Reboot” button to go to Advanced Boot Options. Select “Troubleshooting” > “Advanced Options” > “Boot Settings” > “Reboot”. In the boot settings menu, select “Enable Safe Mode with Command Prompt”. In the Command Prompt window, type net user administrator /active:yes to enable the Administrator account. Then restart the computer and log in with the Administrator account.
Modify administrator privileges:
Once you are logged in as an administrator, you can use the “Local Users and Groups” management tool to modify the administrator privileges of other accounts.
Adjust UAC settings
Open the UAC settings:
Once you are logged in as an administrator, you can find “User Account Control Settings” via Control Panel or Search.
Adjust the UAC level:
In the UAC Settings window, you can move the slider to different positions to adjust the UAC strictness. Lower settings will reduce the number of UAC prompts, but may reduce the security of your system.
Turn off UAC completely (not recommended):
If you want to turn off UAC completely (although this is usually not recommended because it reduces the security of your system), you can do so through the Group Policy Editor. Open the Group Policy Editor (gpedit.msc) and expand it to Computer Configuration > Windows Settings > Security Settings > “Local Policies > Security Options. On the right side, find “User Account Control: Run all administrators in administrator approval mode” and set it to “Disabled”. Then restart your computer.
Best regards
