Been diagnosing this for a week now. Came across these forums multiple times. I see in various threads how you run SFCFix with a zip file of the "clean" files. I don't know what dependencies the SFCFix tool has or needs, but I can't get the program to even run. I get a SFCfix has crashed message so I can't even run the program. I have done local WIM DISM attempts, multiple sfc scans and reboots. But from what I can tell SSDPAPI.dll is used from svhost.exe to run BITS. that continues to fail. My windows update I have to manually start and then it stops after two minutes. I attached a snippet of my CBS log which shows the "problem" which is a CSI corrupt payload and that the WinSxS folders that contain the files have mismatching hash values to the files in System32 folder. I can only assume that this is causing these DLL's to not function. It is my understanding that I should be able to run DISM restore healths to fix my winsxs files, but because windows update won't stay up I can't reach out to windows update for those files and I fails when I try to pull it from local source WIM folders. Anyway, attached is the SFCFix error screenshot just by trying to run the program (from desktop as admin) and a txt file of the corrupted CSI payload and the reference to the hash mismatches.
Finally, I have tried taking ownership of the winsxs folder with the SSDPAPI.dll and copy, but it won't let me because it says its in use. even though I am not touching the DLL that is in system32.
