Changing from Windows 32-bit/x86 to 64-bit/x64

A blocker that still exists and will persist in the future is trying to perform an in-place upgrade from an x86 to an x64 OS. In fact, you will be able to perform an in-place upgrade, but you will only be able to keep your documents and not your apps. There are too many changes with different paths, dual structures in the registry, and so on to keep this blocker going into future releases. So if you need to upgrade to x64--and trust me, you want to upgrade to x64 as new hardware will no longer provide x86 drivers and a lot of features are not available in x86--you can keep your files or go with a wipe and load. Microsoft will still support a 32-bit version of its client OS, but features requiring Hyper-V, such as Virtual Based Security, Credential Guard, and so on, will only be supported on the 64-bit version.
