Windows 7 update error - 80092004 - KB4340558

[stockhausen]

When running Windows Update on Windows 7 I keep getting a failure notification with the error code 80092004.

The "Important update" of which it is a part is:
2019-10 Security Monthly Quality Rollup for Windows 7 for x64-based systems (KB4519976).
Research suggests that this particular error relates to KB4340558, a problem with .NET.

As it happens I am not aware of any .NET "issues" affecting me but would like to resolve whatever is causing the update to fail . . . has anyone else encountered this problem and found a way round it?

I did wonder whether I could "remove" all traces of .NET form my system somehow and then download the current version of .NET - would that work and if so, how would I do it?

Thanks in advance

I am now getting "Windows 7 Update Error Code 8009204" on "2019-09 Security Monthly Quality Rollup for Windows 7 for x64-based Systems (KB4516065)".

Having done some research I get the impression that this may be due to changes actually made by Microsoft
Since last August they sign packages only with SHA-2 having decided to drop SHA-1 as a result of known weaknesses. It appears that this may cause update problems with anti-virus packages.
