Copying regedit.exe to in order to run it.

  1. Double-click on the My Computer icon. In the window that appears, double-click on the C drive.
  2. Look for a folder named Windows if you are running Windows 95, 98, or ME, or a folder called Winnt if you are running Windows NT, 2000, or XP (if you don't see either a Windows or Winnt folder, then go back to step 1 and look in another drive). Double-click on the folder.
  3. Look for the file called REGEDIT.EXE. You may need to click on the hyperlink "Show files" in order to see the files (the files should be in alphabetical order). Once you find it, right-click (using the right mouse button) on it, and from the menu that appears, choose Copy.
    • If you find REGEDIT but cannot see the file extension .EXE at the end of it, you must make file extensions visible on your computer before you proceed. Instructions for making file extensions visible.
  4. Right-click in a blank area in the window and choose Paste. A file should be created named Copy of REGEDIT.EXE
  5. Right-click on Copy of REGEDIT.EXE and choose Rename from the menu that appears.
  6. Type "" (without the quotation marks) and hit the Enter or Return key on your keyboard.
  7. Close all your windows.
  8. Repeat all of the steps under "Starting the Registry Editor," but in step 3 type "" instead of "regedit" (again, without the quotation marks). You should now be able to open Registry Editor and edit the registry--proceed to the section Backing Up the Registry.
  9. On Windows NT 4.0, 2000 and XP computers, there is another version of the Registry Editor that can be activated by typing "regedt32" instead of "regedit". Using regedt32 gives you access to additional registry keys, but you rarely need to access those additional keys.
