Upgrade to 64 bit


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.

Thank you.

Is that an upgrade or are you suggesting that since I need to perform the reinstall anyway?
You must reinstall to change to 64-bit from 32-bit.  You cannot just upgrade

AS per Microsoft, you can upgrade Windows, but they must be of the same bit type (32 to 32 / 64 to 64). As previously stated, you cannot go 32 to 64.
Same is true for installed applications.  They do not upgrade from 32 to 64 bit and must be reinstalled, even if they don't have a specific 64 bit version.   For some apps you will need new installation media/files.  Some include the ability to install either 64 bit or 32 bit from the same media/file.  

Even some portable/standalone apps have a different set of executables for 32 and 64 bit versions.
As noted at the beginning here you must back up , wipe , and install 64-bit fresh
and verify if your desktop is able to handle 64 bit, motherboard + cpu !
make sure you back up everything as previously said in this thread... also take note of all the softwares and configurations.
Thank you for the information. It was helpful.
You are very welcome and I was happy to help.
