Summary: Upgraded from win XP, and was forced back to XP. Had problems with Windows-7 from the get go. I have windows 7 in my laptop no problem My desktop computer did not like Windows-7 and ran super slow and in the end I gave up and re-installed XP, now my desktop works great again. I tried larger HDs more ram nothing helped.

Summary: This software is OEM System Builder. I spent several frustrating hours on the phone with TigerDirect and Microsoft discussing if I could legally install this on my home built PC without registering with Microsoft as a System Builder. The end result is that pay no attention to the paranoia that you can't install this on your own PC. I had absolutely no issues installing this software on my home built Win7 64bit capable machine.
