Okay. The idea is simple:
A batch file runs constantly, monitoring newly executed programs.
If the installation directory of the newly run program = ("D:\Blocked") do (
End program)
I'm a little ashamed to say that I don't have any code yet

I can't think of a reasonable/cost effective way to do this...
Obviously, I could do with discarding startup/already running program.exe's from the (tasklist(?)) search,
Especially if one (a search) is to be performed every second or whathaveyou...
And Taskkill presumably... Unless there's a way to have the .exe paused, via batch, until the check is complete?
As always, thanks for any help.
P.S.
This will not to be used as a replacement for any sort of security software.
And so, I will not require advice on whether or not it will be effective in such scenarios.
