Change default program installation folder [registry hacks]

Whenever you install any programs in your computer, the installation will be done in program files folder. But what if you wanted to change this setting. There is a simple registry hack in order to change the default installation folder.
First, start registry editor by typing regedit.exe in run menu. Then, go to the following:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion



Now, change the value of ProgramFilesDir to whatever you prefer. Now exit registry and reboot your system to have your default software installation folder changed from program files to that of your choice.
Thanks.
