Hello and welcome.

We have no idea what the answer to this might be. Above all, what connection does this have to Qt anything?

Hi
There is nothing in Qt to block another exe from starting,

For that you need to write a low level driver like a virus scanner and block it there.

It is possible to block apps via the registry
https://www.wikihow.com/Block-an-Application-or-.EXE-from-Running-in-Windows

However, when you lock or unlock this way, the OS has to be restarted.

I think the same applies to AppLocker
https://docs.microsoft.com/en-us/windows/security/threat-protection/windows-defender-application-control/applocker/applocker-overview

BUt I don't know for sure.

Isn't there something like that shipped with Windows?
Child restrictions or how it's called? You can block websites and programs there

Running the application GameFastF.exe is something done by the CreateProcessW API call (or similar) on Windows, and equivalents on other platforms. Qt provides QProcess to give you a cross-platform way to start another process.

It is not clear whether your are saying that the GameFastF.exe program does not start when you use QProcess to launch it, or whether you you want your Qt-based program to somehow stop the GameFastF.exe from running no matter how it is started.

In the first case, you would have to show your code and the QProcess::error(), exitStatus(), and anything else that relates to the problem.

In the second case; whether the operating system will allow a specific executable to run is outside the control of Qt. If you want to blacklist certain executables then AppLocker or Windows Defender Application Control (WDAC) may be places to look.
