If you ever faced this strange issue in Windows where the Yes button is disabled in UAC dialogs, you might be very confused as to why that is, especially when your user account is already an Administrator level account. In this article, we will see how this problem can be fixed.
- Reboot Windows into safe mode. You can read these articles for further reference:

- How to boot into Windows 8.1 safe mode
This will allow you to operate your computer as Administrator.
- In an elevated command prompt, run the following command:
net user administrator /active:yes
This command will enable the built-in Administrator account.
Tip: See how to open an elevated command prompt in Windows 10.
- Now, type the following command:
net user administrator password
This will reset the Administrator account's password and make it empty.
- Reboot and sign in as Administrator.
- While you are signed in with the Administrator account, type the following command in an elevated command prompt:
net localgroup Administrators YOUR_USER_NAME /add
This will add your user account into the local "Adminstrators" group.
- Restart the operating system and sign in with your regular credentials, assuming it is same account you specified above.
That's it. This should resolve the issue and the button "Yes" in the UAC dialog should become accessible. It will no longer be greyed out.
