Windows 10 UAC Yes Button Greyed Out: When You Cannot Approve an Administrator Prompt

You try to install a program or open a system tool, and the User Account Control prompt appears asking “Do you want to allow this app to make changes to your device?” But the Yes button is grey. Only No works. When Windows 10 UAC Yes button greyed out blocks approval, your account has lost the right to elevate, or something is interfering with the prompt.

The Yes button is only available when you are signed in as an administrator. Standard accounts see a password box asking for an administrator’s credentials instead. If your account was downgraded to Standard, or the only administrator account was disabled, there may be no way to approve the prompt.

A rarer cause is screen overlay software. slot mahjong Windows greys out buttons on the secure prompt if it detects another program drawing on top of it.

Identifying which applies tells you how to proceed.

Why This Happens

The Yes button is unavailable for these reasons:

• Your account is a standard user, not an administrator.
• The built-in administrator account is disabled and no other admin exists.
• An overlay, screen dimming app, or remote tool draws over the prompt.
• Parental controls or a policy restrict elevation.

Family Safety child accounts are deliberately blocked from approving changes.

Start With These Basic Checks

Check your account type.

1. Open Settings > Accounts > Your info and look for “Administrator” under your name.
2. If it says Local account or Standard user, ask the person who manages the PC to sign in and approve.
3. Close screen filter, blue-light, or remote control apps and try again.
4. Restart the PC and test the prompt.
5. If another administrator account exists, sign in with it and change your account type in Settings > Accounts > Family & other users.

Going a Step Further

Look at overlays, family settings, and prompt policies.

1. In Task Manager, end screen dimmers, colour temperature tools, screen recorders, and remote support apps one at a time, then trigger the prompt again.
2. If you use a Microsoft family group, ask the family organiser to check your role at family.microsoft.com, since child accounts cannot approve changes.
3. On Pro editions, an administrator can open secpol.msc and go to Local Policies > Security Options.
4. Check “User Account Control: Behavior of the elevation prompt for standard users.” If it says “Automatically deny elevation requests,” set it to “Prompt for credentials.”
5. If your own account lost its administrator role and no other administrator exists, use System Restore from the recovery menu to return to an earlier point.

A Word of Caution

Never use unofficial password or account hacking tools from the internet. Back up personal files before a reset, and keep at least two administrator accounts on shared PCs.

Final Thoughts

A greyed-out Yes button usually means your account is not an administrator or an overlay is interfering. Close overlays, sign in as an admin to fix your account type, and use System Restore if no admin remains.
