Can I upgrade from Windows 7 32-bit to Windows 7 64 bit without reinstalling all of my software? [duplicate]
No.
X86/32-bit to X64/64 bit is not supported in any version of Windows through either upgrade or anytime upgrade.
Your only option would be to do a fresh install - however, if I was you, you should format the drive first to really get a fresh start.
You can however use Windows Easy Transfer which should make it easy to transfer your documents and reinstall your programs.
Short answer to your title question: No.
More detailed answer as to what I believe to be the easiest way to migrate: This is fairly easy to do, but you need to do a clean install. That means you need to
- Backup your data and programs
- Insert the x64 disc and restart your computer
- Boot into the disc and install Windows
- Restore your data and reinstall programs
There are built-in tools for backing up your data and your program settings and there are third-party tools to reinstall all your programs. For example, Laplink PCMover will automatically reinstall your applications, but I don't know much about it (I only read about it in Ed Bott's Microsoft Report and I don't know any more about it). Note: I in no way endorse this software and I do not know if it will work for this purpose.
