Windows 7 arrived yesterday, should I install 32 or 64bit?

Will 64bit OS allow me to use my full 4 gig of RAM? On XP 32 I'm using 3.25 gig or something.

On another topic; how do I 'uninstall' windows 7. I have the retail which only allows 1 install at a time. How does the OS know it is only installed on one PC. If I do a hardware upgrade, how do I deal with this?

Install the 64bit version, will see your 4gb RAM no problems.

So I wouldn't see full 4 gig with 32bit version?

Ok well thats 1st bit solved.

Anyone got any idea about 2nd part? Not have retail OS before, only OEM

You can upgrade your motherboard and change PC with a retail version and the only limitation is it can only be installed on one PC at a time.

Yes and how do they know when it's installed on one PC at a time?
