In windows 7 actually i tried to change default installation location so that i have done the following steps 

1.    Start Registry Editor by entering “Regedit” in the search All programs.

2.    Locate the following:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion

3.    Right click on the value named ProgramFilesDir & change the default value C:\Program Files to the path you want to install all your programs in.

4.    Click OK and Exit.

changed my disk C: to F:

and after restarting my machine when i tried to open regedit.exe  it shows as "*windows cannot find'C:\windows\regedit.exe'.*Make sure you typed the name correctly, and then try again." and also when i try to open applications through administrator  it  popups the  same  as windows cannot find. How can i revert it? please help with this.

    I would not change the default installation location for programs. There are better ways in case you're running out of disk space.

    Does the file C:\Windows\regedit.exe exist?

    You can reverse your changes with System Restore (rstrui.exe).

    Experimenting with the Windows Registry is risky business, especially if you don't create a backup and/or system restore point first.  You can easily turn your computer into a brick.

    Does "changed my disk C: to F:" mean that you made that change at the registry location mentioned in step 3 or did you make that change elsewhere?  If elsewhere, where did you make that change?

    It sounds as if you are able to get into Windows. 

    • What happens if you click Start, type C:\Windows into the Search box, and press Enter?
    • What happens if you click Start, type F:\Windows into the Search box, and press Enter?
