Hi,

I am currently busy with a update problem on my dutch forum. The CBS.log of the TS shows the following. I can provide a link to the topic if that's convenient?

Code:
2021-05-02 16:28:36, Info                  CSI    00000007 Manifest hash for component [l:98 ml:140]'wow64_microsoft-windows-t..es-commandlinetools_31bf3856ad364e35_10.0.19041.1_none_a4f6113bccc284b7' does not match expected value.
Expected:{l:32 b:66fa942bd32e0dd187308265b232a5c6b97de2e23f2ce003df8cfebf30842b11}
Found:{l:32 b:6bed6ecd7fb8a2ef5778c39309a072b28fd839f212be56b3537c590866129ce7}.

On my system, and install.wim from the ISO (Win10_2004_Dutch_x64) is the HASH of 'wow64_microsoft-windows-t..es-commandlinetools_31bf3856ad364e35_10.0.19041.1_none_a4f6113bccc284b7.manifest' > 6F603B158E59A4E5D16061CE7EA961E53313D56C9D50FD87EB2022E057B8A66A

This file-hash is not matching with the hashes that the CBS.log shows. Now comes the strange thing?

I ran the following script with FRST (on my own PC and two others) and this shows me this result.

The command 'certutil -hashfile' shows me the same file-hash, but the REG query is given the 256-hash that matches with the expected HASH in the CBS.log from the TS?

Am i correct as i think that this entry in the register of the TS contains the incorrect HASH?

Thanks in advance.. (y)
