Prevent determined software to run?

[kayo7]

Is there a way to prevent certain program to run by pressing a key, (like the opposite of the command Run)?

I'm trying:

a::
Sleep 1000
WinClose, chrome.exe (<--Just an example)
Return

With this, the program (in this case Chrome.exe) opens briefly, and then it closes. There is a way to block the program before it opens?

You can attack it at the process level. Or, just uninstall it or turn it's respective service off (if it has one). But, your example for me does not show the window before it closes like you're indicating.

I understood that attacking at the process level is better, thanks for the tip.

But I want to know if instead of closing the program, I can prevent it from opening.
