Minimum possible permissions for a Win7 user to login?

0

On my Win7 Pro x64 system, I would like to run a program I have 99% confidence in (specifically, Blitzgewitter by Titan). However, on the off chance of a trojan, I would like to run it in a sandboxed user account.

What are the minimum necessary permissions for a user account (say, "scener") to login, download the file to %USERPROFILE%, and run it? I'd appreciate any advice before I start trying something since I don't want to get into login failures.

I have two thoughts:

  1. Remove scener from the Users group and set Allow Read for scener on C:\Windows and C:\Program Files, Allow RW on %TEMP%, and Allow All on C:\users\scener.

  2. Leave scener in the Users group but Deny everything except R on C:\Windows and C:\Program Files and RW on %TEMP%.

What say you?

1If the software is to run sandboxed like this anyway, I would strongly consider running it inside a VM. Then you can isolate it as much as you want to, and not have to worry about specific permissions. – a CVn – 2015-08-08T13:36:00.503
