windows 7 32bit - windows 7 64bit

[Johny2Fingers]

Is there a way to upgrade my windows from the 32bit version to the 64bit one without booting the iso from an usb stick or using the optical drive?
Im not home at the moment and I dont have either of those on me at the moments. Trying to upgrade to the 64bit version of the OS so I can use more then 4gb of ram.

No, it needs to be reinstalled.

32 to 64bit isnt like going from Home Premium to Professional where all they are doing is unlocking some features, its a complete change to the way programs interact with the OS and how it "works". You need a completely new install of 64bit Windows if you want it.
