Occasionally you may find that a nasty virus changed your desktop and removed your ability to run regedit.exe.

There are several ways to re-enable it which depend on your operating system and set up.

• Start -> Run -> gpedit.msc -> User Configuration -> Administrative Templates -> System -> Prevent access to registry editing tools -> Right Click Properties -> Disabled
• Run the following command:

  REG add HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /t REG_DWORD /d 0 /f

• Create a .reg file that contains the changes to switch on the registry editor then run it.

  Windows Registry Editor Version 5.00

  [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
  “DisableRegistryTools"="0″
