Hi, as the title suggests im in a little bit of confusion on whether i can upgrade my current 32bit version of Windows 7 to the 64bit version. About a year ago i purchased the Windows 7 Home premium upgrade package to run on my Dell desktop that was running Vista home Premium at the time. The upgrade package came with 2 discs and i chose to install the 32bit version as my Vista version said it was 32bit. Now after some time and getting more familiar with my computer i have become aware that it is infact compatible with the 64bit OS software. From what ive read and understand if this was installed it would improve my computers performance so the what i need to know is can i utilise the second disc that came with my upgrade package?
