I am using Win7 Ultimate on my desktop at home. It's 32-bit. Just take this one caveat: this particular installer CANNOT upgrade Win XP - it should be a fresh install.

Just check the web if there are available Win7 drivers for all your devices. Secure them first before you "migrate" to Win7. With all the needed drivers at hand, I'm sure you'll do fine.

Good luck!

'''''' You will be lost looking for features from XP that you want but most are still there (just renamed or in different places) and you will find them after a while. ''''''

This is why I hate change system.... and also wonder why they have to modify all.......... I run my XP in ''old win'' style because i love it!!!! and see no gain in all those feature.....
