Registry edition disabled by Administrator (WinXP / Vista / Win7)

The value for disabling Windows registry is named "DisableRegistryTools". It is a DWORD value in the key

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersión\Policies\System

It has two values: 1 and 0, where 1 is for disabling the edition and 0 for enabling.

For enabling it again, in Windows XP we have to use the command line (start/run/cmd.exe) and “reg” command. The full command to use is this:

reg delete
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System  /f /v DisableRegistryTools

You have to type it in a single line.

At last, I have to say that this key is modified by several viruses, so it is a good choice to scan the machine for viruses (see our links section).

Note: the steps from above can be done in an automatic way by downloading this script from our repository.
