If Smart App Control is enabled in Windows 11, it may block apps like TPS. This happens because Smart App Control uses automated criteria to determine which applications are considered safe.

Smart App Control (SAC) is a security feature in Windows 11 designed to help protect your computer by blocking apps that may pose security risks. In some cases, it may also prevent trusted applications—such as TPS—from running.

If you choose to turn off Smart App Control, your system will continue to be protected by built-in Windows security features, including Microsoft Defender and other standard protections.

Turn Off Smart App Control 

1. Click "Start".
2. Open "Settings".
3. Go to "Privacy & Security".
4. Click "Windows Security".
5. Select "App & browser control".
6. Click "Smart App Control settings".
7. Choose "Off".

You may be asked to confirm with administrator permissions.

Once Smart App Control is turned off, it cannot be turned back on unless you reset or reinstall Windows.
