Hey, I have a not-so-reliable-sourced key for an Anytime Upgrade to Windows 7 Ultimate, if I make a restore point in my previous version of Windows 7 (Home Premium 64-bit) can I go back to it if the Ultimate version turns out to be not geniune? Thanks in advance.
No.. I afraid it is not possible and You cannot go to Previous OS'es. Once a new OS is installed means all restore are reset and the first restore point will be at the installation point of your new OS. Say Windows 7.
