OK, I know I had a program to do this before I reset my computer, but I have tried to remember and remember for the past month, and I can't.
I am looking (or, trying to remember) for a program that allows me to install a program in a 'virtual machine' basically. So, if I want to install an untrusted program, I can simply right click, open with PROGRAM, and it installs it into a virtual 'place' on my hard drive.
I need it to be free and run on Windows 7 64 bit.
