I currently have 32 bit, but I want to upgrade to 64 bit. I bought Windows 7 about a year ago, the digital version. I was wondering how I can get from 32 to 64 bit, do I have to do a complete wipe and reformat with 64 bit? If so, is there a clear cut option when reformatting to choose 64 bit? I don't remember seeing anything last time I reformatted.
Yes, you will have to do a complete re-install
You will have to choose the custom install option during installation. Then format the the old windows partition using "format drive" in "advanced options"
As a side note, you can use the Windows Easy Transfer tool to transfer old accounts and documents to the new system
Do I download the 32 bit.exe files or the 64 bit.exe files?
Most 32-bit programs work perfectly in 64-bit Windows . However try to get the 64-bit versions when possible.
The only exception are the drivers. You need to download & install the 64-bit drivers for all the hardware you have. 32-bit drivers won't work with 64-bit OS and vice-versa.
