There is indeed a way, but it is not simple, it is not easy, it involves separating the Windows 7 main system folders from the OS and placing them on another drive, it involves partition resizing, and lots of registry editing, and once again (no offense intended) I get the feeling that your experience level isn't up to it.

Set 7 Free is targeted toward and written for advanced users only. The instruction set must be followed step-by-step and in the proper order. Read the warnings carefully. It does indeed work, and has worked for many people, but you can also make your system unbootable. It is a stable, solid and crisp setup when done correctly. But you may well decide that you don't want to tackle it, and that might be a good thing.

You have been warned.
