I try out a lot of software and this tends to clog up Windows. So I thought (rather than breaking this bad habit) that I'd start using some Sandbox software to isolate software I'm trying out.
Goal: to be able to completely remove an app so that (to Windows) it's as if it were never installed.
I see that there are a variety of them.
Sandboxie (freeware) - Sandboxie is one of the most talked about and widely used free applications in this group. It's not so much designed as a "total desktop" solution, but as a way to isolate certain programs that pose a risk - like web browsers. Podcast on it: http://www.grc.com/securitynow.htm#55
Trustware Bufferzone Similar to Sandboxie, Bufferzone is more about isolating threats from the internet than completely locking down your system. It's designed to isolate apps like your web browser, email, and peer-to-peer programs. Downloaded files inherit Bufferzone's protection, so if you install something that was downloaded from a protected app, it becomes protected as well.
