My PC with Windows XP (32 bit) was destroyed when my Antec SmartPower 2.0 500 Watt Power Supply failed. Since I only have used Windows XP, I would like to know three useful features of Windows 7 (64 bit) besides the ability to address more memory. Old PC had 2GB and the new PC has 8GB. I am not interested in Microsoft marketing says, but what real people say about Windows 7. I have an HP Laserjet 1012, that is quite old, but still fine for my needs and concerned about support for that.
