Fix the Yes button error in UAC disappearing or graying out in Windows 10

When you try to open a program with admin rights, the User Account Control (UAC) dialog box appears. But sometimes the Yes button in this dialog box may be missing or gray.

The cause of the error

This problem usually occurs when no other admin account exists in the system and your account no longer has administrative rights. In this guide, TipsMake will show you an easy way to troubleshoot that UAC privilege issue.

Fixed a bug where the Yes button in the UAC disappeared or turned gray 

1. Open the Command Prompt window without admin rights. Enter the following command and press Enter.

SHUTDOWN /R /O -T 00

2. The computer will log you out and display the Choose an option screen . Click on Troubleshoot.

3. Select Advanced options.

4. On the next screen, click Startup Settings.

5. From the Startup Settings window , click Restart.

6. When Windows restarts into the Startup Settings screen again, press 6or F6to select 'Enable Safe Mode with Command Prompt' .

7. Although the built-in Administrator account is disabled and hidden, this account will still be displayed on the Safe Mode login screen . You can click on it to log in without a password.

8. After logging in, the Administrator Command Prompt will open. To fix the problem of the missing Yes button or grayed out in UAC, enter each of the following commands to change your password, change your account to admin and activate it.

net user YOUR_USER_NAME /active:yes

9. Restart the computer as usual.

If you previously set a password on the built-in Administrator account and you cannot remember the password, the above method will not work.
