I was checking the secret registry keys with a registry editor (regedit.exe will not show this kind of information). I found this line: HKEY_LOCAL_MACHINE\SECURITY\Policy\Secrets\L$RTMTIMEBOMB A Google search showed only one German site with a brief comment on it. Comment was that it was part of Windows, not to worry. But the Microsoft site has nothing on it. Would anyone care to shed more light? Why would Microsoft choose such an alarming name?
