[out-of-ideas]

did you use the one 15+ years ago? what else can you tell about it?

sandboxie is quite old yes; and `dog` vs `god` LOL; did you drop your question in to an LLM? copilot gave me (re dog) winpatrol - though i dont think it has task any application based api stuff https://www.bleepingcomputer.com/download/winpatrol/

there was also things like vmwares thinstall which would wrap up an exe's installation process to make a more or less portable application (edit was here)

there were apps like InstallSheild's system monitoring software which could really monitor a systems changes before and after and build installations of files/registries changed

then there stuff like Deep Freeze which made windows more or less immutable (to a degree) where a reboot would "restore" the system - useful in schools ect

I used Gemini to find stuff out. But WinPatrol was actually what I vaguely remember, I think...I probably remember it doing more than it actually did, my recollection was that you would install it, run it, and it could intercept, I think, applications you wanted to run. Or you'd run it through WinPatrol?

That's why I said Sandboxie is closer to in spirit to what I remembered.

It's been closer to 20 years since I used it, I remember a lot of popups, I think, and you could break programs in all sorts of creative ways :-)))
