    Changed my programfilesdir and now I can't do anything

    Hello guys,

    So I tried to change the installation path of everything to my 2tb external D: drive becuz my hard drive only has 150gb.

    I did this:

    Open regedit (Start > Run > "regedit"). Then find "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion". Now look in the right pane. Change "ProgramFilesDir", "ProgramFilesPath", "ProgramW6432Dir" and "ProgramFilesDir (x86)". If your secondary drive letter is D:\, then change them to "D:\Program Files", "D:\Program Files", "D:\Program Files" and "D:\Program Files (x86)", in that order that I just mentionned. You should be good to go from here.

    However I think I strayed too far from the path and goofed something up along the way because I cannot do anything on my computer that uses the c drive and when I try to go back to change it, regedit doesn't work. Also even tried to system restore and its just unresponsive and I can't do anything.

    Welcome to the forum.

    Microsoft does not support or recommend this procedure. It is provided for exceptional circumstances, not for general use. Unfortunately many Internet articles miss that part.

    There are issues beyond those mentioned.
    Sorry, I do not have a solution for your problem.

    You might be able to restore the backup copy of your registry, then reverse the regedit.
    No guarantees whatsoever. You are in perilous territory.

    Otherwise you could try editing the registry offline. (You can research that).

    Whether you'll end up with a reliable system is another matter.

    If you had been using disk imaging, which we constantly and strongly recommend (e.g. Macrium Reflect (free) ) you could have restored your system from a previously created image relatively painlessly.
