I've actually been using the Windows 7 / IE9 version of this for a while. There is a nice simple install w/snapshot that I utilized on both my Ubuntu machine and my Mac. It takes a snapshot before powering the machine so once your 90 days is up, you can just roll the snapshot back.

Edit: I mainly use IE to interact with work's IE-only CRM/ticket system.
