Windows 10: Cannot install cumulative update for Windows 10 version 20H2 KB4598242

About 5 days ago, I came across a random blue screen while working on my personal computer. It seemed like a new update was available, so I immediately started the installation process. The status bar reached 100% but then suddenly failed with an error code of "0x8007045d"

Cumulative Update for Windows 10 for x64-based Systems (KB3156387) will not install

Anyone else having problems getting the Cumulative Update for Windows 10 for x64-based Systems (KB3156387) installed? This update has been failing for me & doing a failed to update after downloading & reboot, then rebooting & removing the update.

V 10.0 build 10240

 

Cumulative update KB4598242-OS Build mismatches-W10 20H2

This is what I've done to date.

1- downloaded the update reset batchfile from the source given, and run it.
2-immediately rebooted the machine
3-downloaded the relevant ssu, although this is listed as installed in Control Panel > Programs. Running that msu confirms that it's already on the system.
4-downloaded the KB4598242 msu from Microsoft, and run it. It started Ok but failed with the same error 0x8007000D
5-checked with sfc /scannow - no problems reported.

In other words, I've stepped through the suggested processes, but still end up with the update failing to install, and with the same error as when update attempted through WU.

I may try the whole process over again, before attempting anything else.

Maybe try with the Windows update mini-tool, found here http://www.techpowerup.com/forums/t...dows-10-automatic-updates-and-spyware.218745/ , thanks to Mussels. it installed perfectly for me last night.
