[SOLVED] DISM and SFC fail - maybe crypt32.dll corrupt?

[ngunn]

Hi There,

I'm trying to repair a Windows 10 system that's showing all kinds of issues. I think I've tracked it down to a corrupt crypt32.dll file? The cryptographic services service keeps crashing and I've found the following in the CBS Log:

21-09-01 09:45:20, Error CSI 00000063 (F) c0000242 [Error,Facility=(system),Code=578 (0x0242)] #4722194# from Windows::Rtl::SystemImplementation:irectFileSystemProvider::SysReadFile(h = 978 ('\Device\HarddiskVolume4\Windows\WinSxS\amd64_microsoft-windows-crypt32-dll_31bf3856ad364e35_10.0.19041.844_none_39670dfa3ca4d618\crypt32.dll'), evt = 0, apcr = NULL, apcc = NULL, iosb = @0x8f0ed7be20, data = {l:0 b:}, byteoffset = 0, key = (null))

I've run chkdsk and multiple sfc/dism but these both fail before completing?

Any ideas?

Thanks!

Looks like I fixed it! Firstly I tried replacing the winsxs file with one from another machine. This seemed to fix DISM, but SFC was still failing. When I finally ran SFC /scannow offline from a windows setup/repair prompt it was all fixed!
