Did you run this Upgrade Advisor?   [URL]   .
Hi all, I am having Inspiron 1525 laptop. I want to upgrade my OS to Windows 7. When I tried to know the compatibility of my system for Windows 7 then gives this " Tested for Basic Windows 7 Functionality". I didn't understand its meaning. Is it telling me that I can upgrade to "Windows 7 Basic Edition" or my system is able to perform basic functionality of Windows 7.
