I have a desktop PC with Windows 7 Pro 32 bit installed. I would like to upgrade to the 64 bit version to take advantage of all the RAM my motherboard will handle. I have several programs that I would rather not have to reinstall. The Windows Anytime upgrade option is missing and I have tried registry fix for this and have aldo made the changes suggested in gpedit. No matter what I can't get the anytime upgrade option to appear. How can I perform this upgrade without losing everything? I have alrady performed a Windows backup and I have transferred data to an external drive using easy transfer.
