Error Code 0x80073712 installing KB4041681 & KB4041083

Error is happening on Windows 7 SP1 x86 running in a VM on Orcale Virtual Box.

Getting an error Code 0x80073712 installing KB4041681 & KB4041083 through Windows Update. I have tried manually installing these updates, I have tried just about everything I can find and cannot resolve my issue. I'm also getting the same error code when I try to install Visual 2017 Build tools or .NET 4.7.

Results of running System File Checker

c:\Windows\System32>sfc /scannow

Beginning system scan.  This process will take some time.

It looks like others have got help with similar errors by posting the error and their CBS.log. Uploaded the truncated version of my CBS.log here. https://1drv.ms/u/s!Ai9R9F0A3bajhycmT_DyVhzZA9Ww

There are four files that seem to get repeated in the log as being corrupted

cryptsvc.dll
cryptnet.dll
d3dcompiler_47.dll
wintrust.dll

Here are the first detailed entries in the CBS.log reporting the file corruption.

@magicandre1981 identified in the comments that cryptsvc.dll, cryptnet.dll & wintrust.dll came from the May Rollup

I did some Googling of x86_microsoft-windows-directx-d3dcompiler_31bf3856ad364e35_6.1.7601.23796_none_eb8e769493af6438\d3dcompiler_47.dll and this pointed me back to KB 4019990 where I was able to extract a good copy of d3dcompiler_47.dll from.

2. Extract files from update

I first used

expand windows6.1-kb4019264-x86_aaf785b1697982cfdbe4a39c1aabd727d510c6a7.msu -f* c:\temp\kb4019264

Then

cd c:\temp\kb4019264
expand Windows6.1-KB4019264-x86.cab -F:* .\kb4019264\Windows6.1-KB4019264-x86

3. Replace

I found each of the dlls in the Windows6.1-KB4019264-x86 and then copied it to the correct location in C:\Windows\WinSxS. For each file

a. Set Owner of folder and file to myself

e.g. C:\Windows\winsxs\x86_microsoft-windows-cryptsvc-dll_31bf3856ad364e35_6.1.7601.23769_none_785f66471253418f

For me the folder was already there, there was just no file present at all. I'm guessing others might see the folder completely missing or the folder and file present, but file being otherwise corrupt. Added myself as a user on the folder and gave myself full control of the folder by going to folder properties and using Advance button on Security tab

b. Copied the good copy of the dll to the folder.

c. For consistency and security, I changed the owner of the folder and the new file just created back to NT SYSTEM\TrustedInstaller user and removed myself as a user on the folder and file

I was now able to successfully install all pending Windows Updates including KB4041681 & KB4041083 above, and install .NET Framework 4.7 and VS 2017 Build Tools.
