Question: Win 7 Upgrade On A New Home Built Computer.

Here's my history and my question.

About six years ago I built my first desktop. I bought and installed a copy of XP.
About a year ago I bought and installed an upgrade copy of Win 7 on the same desktop.

I just built my second desktop. Will this upgrade copy of Win 7 install on this new computer (the boot drive is brand new)? The old desktop is not in service so I will not be using the same copy of Windows 7 on two computers.

If it won't install, could I install the old XP and then do a clean install of Win 7 over it?

Can I install a 64 bit Win 7 over a 32 bit XP (the processor supports 64 bit).


Your advice is very much appreciated.

    You may have to call MS and explain the situation if it doesn't let you activate it, but so long as you aren't using the same copy on 2 computers, they should allow it.
