Ensure you reinstall Windows completely since certain programs run differently between 64-bit and 32-bit versions. Is Windows 7 64-bit actually larger than 32-bit?

It's approximately 20-30GB, which means it's larger than expected. I'd recommend a fresh installation if possible.

Other factors include hibernation files and page files, not just the operating system using disk space.
