I'm looking for a bit of assistance here bcoz' I would like to upgrade to Windows 7. Right now I'm using Vista Ultimate 64 bit. Now, if I read this correct over the net, I can do the upgrade with no hassles as long as I have the equivalent of Windows 7 Ultimate 64 bit right? Would I still have to back up my files just in case something should go worng? Your advice is greatly appreciated. Thanks.
