I've been using 'Returnil Virtual System 2008 Personal Edition' on my old laptop with WinXP. I now have a new Win7 laptop and am wanting the same thing - but I can't even tell from the website what version I want. Seems things are done differently using Windows native SysRestore. Is there still a version that basically just resets everything to a "perfect state" with every reboot? I keep seeing versions with AV, etc. I just want to be back where I was with a clean system every boot. What do I get? Or, has it changed and you no longer offer that once so beautifully simple system?
