ok, i'm going to download the ms patch for msblaster

http://www.microsoft.com/technet/tre...n/MS03-026.asp

cause i forgot to do it for my laptop with xp (only did it for my pc). Anyway, i realized there are 2 patches for XP: one for a 32 bit edition and the other for the 64 bit edition. I didn't know there were two kinds of xp's.

How can i know what edition do i have? 32 or 64, where can i check that?
