The values stay the same enabled or disabled. I did find: http://support.microsoft.com/kb/929820 which talks about the registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\Memory Management\PagefileOnOsVolume with a value of 1 is created when you enable BitLocker. However, that key and value stays if you disable BitLocker. So it helps, but still not the best check to use. Thanks for looking zanyterp.
