http://www.microsoft.com/windows/windows-7/get/system-requirements.aspxAccording to http://www.docs.sony.com/release/specs/PCVRX741_sp.pdf, your computer supports a maximum of 1GB of RAM.  Therefore, I'd be very reluctant to upgrade it to Windows 7; I would not want to run Win 7 on a system with less than 2GB, ALTHOUGH it will run on 1GB.  But, go ahead and run the upgrade advisor in Allan's link to get a more detailed analysis.Thx for your input!!!Im gonna play it save and stick with my trusted win xp. Thanx again and happy holidays
