Windows 7 32bit (OEM) - change to 64 bit, how? Tags: Windows 7 Clean Install OEM Last response: November 9, 2009 3:08 PM in Windows 7 Share nightgyr November 9, 2009 2:35:06 PM Hi all I made the mistake of not realising the benefits of win7 64 bit. I have win7 32 bit OEM but I want to clean install the 64 bit version. My questions: 1) How can I attain a copy of 64 bit windows 7 to install? (my OEM disc only came with the 32 bit version) 2) Will my win7 32bit OEM serial key work for the 64bit version? (from what I've read, it seems possible but would like to confirm) Any help would be appreciated. thanks!
