If you would like to re-enable the undocumented value to disable Windows File Protection, you may apply the appropriate patch and then replace the DLL in the 2k/XP recovery console (boot to CD).  Be sure to set the checksum in the PE header by using Bitsum Technology's SetCSUM utility after patching.

How to find the patch offset yourself for current and hopefully future version of SFC.DLL or SFC_OS.DLL:

Search for the hex byte sequence: '83 F8 9D 75 07 8B C6' and replace the '8B C6' with '90 90'. If more than one occurance of this sequence is found, do not patch unless you know what you are doing. Email me at jeremy@bitsum.com for more aid. Please do not email me with instructions on how to actually apply the patches listed here. They are intentionally kept technical to prevent layman modification of windows system files.
