sfc_os.dll is patched (rvyan's) and registry entry is disabled SFCDisable=ffffff9d but after installing some programs, it changes the "SFCDisable" key back to "0" which leads SFC to be enabled. Uxtheme, longhorn transformation packs are such programs. can this registry seeting be locked permanently.. i don't want this to be changed always and annoy me all the time. just disable permanently i had tried dreampack , but it was detected as Virus/Trojan by some AntiVirus i also tried SFCDisable=00000000 SFCSetting=ffffff9d .. in vain.. still popup WFP dialogue I want it to be included in UAXPCD as well
