In my opinion you could well continue running XP as you are not experiencing (or have not described) any issues with it. IF you feel like changing OS, you have no real *need* for Windows 7 Ultimate 64bit, any more limited version (please read as cheaper) would do nicely for your "home" uses. In any case your hardware is (from the little you say about it) on the "slow" side, particularly 2 Gb of RAM, which are more than enough for XP, are a tad bit "tight" for Windows 7 (any version) and I have to presume that other hardware components may not be powerful or fast enough to provide you a positive experience with Windows 7 usb dvd download tool Windows 7 (like Vista before it) has a much greater needs as hardware resources, it will anyway be slower than XP, depending on the specific hardware you have it is possible that this added slowness will be hardly perceivable or enough to make you feel your PC as sluggish. If you post the exact specs of your hardware someone might be able to give you an estimate of how "well" a Windows 7 might run on it. jaclaz Well i have no such reason for upgradation because my win xp working fine for me i am just want to change os to see new windows graphics and other cool features
