HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion

ProgramFilesDir, ProgramFilesDir (x86)

C:/Program Files to

D:/Program Files.

You might want to rethink your partitioning if your C is so small you need to worry about where to install apps. That being said, why mess with system variables anyway. If you create a directory called D:\Program Files, and point your installers to use that folder, your apps will still work fine.
