You would need to get the older version of sfc_os.dll file, search on google, as you have to patch the dll file, it shows you which bytes need patching , more importantly for you it show you the original values, so you could patch them back to normal, then use the registry, although i am not sure how nlite does it, maybe get my sfc and replace yours in safe mode, though mine ends in 0 and not 2160, though mine is def from a sp1 install which is what your supposed to have and not the sp2 one whos file version ends in 2180. sfc_os.zip
