Hi, I am new to this site, first post. I have a PC that currently has windows XP Pro 32 bit installed. I wish to upgrade this system to Windows 7 64bit. Can you help with the following please: 1) How can i check if this PC will support windows 7 64bit? 2) I purchased a windows 7 64 bit home premium edition for system builds only, so will I be able to use this to perform a clean install if my PC supports 64 bit? Thanks very much for the help.
