Change the Default Location for Installing Programs

Basically windows uses the C:\Program Files directory as the default directory to install new programme. However, we can change the default installation drive and/or directory by
using a Registry hack.To do this

• Run the Registry Editor(regedit in run command)
• Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion 
• Look for the value named ProgramFilesDir 
• By default, the value will be C:\Program Files
• Edit the value to any valid drive or folder

Windows will use that new location as the default installation directory for new programs.
