Great.

Open an elevated command prompt.
Copy and paste the following commands into it, press enter after each.

Code:
sfc /scannow
Wait for this to finish before you continue

Code:
copy %windir%\Logs\CBS\cbs.log "%userprofile%\Desktop\cbs.txt"
This will create a file, cbs.txt on your Desktop. Zip this file and attach the zipped cbs.txt to your next post.
 
Try to install KB5027271 again and report the result.
 
Provide a fresh copy of the SOFTWARE hive as instructed in message #40.
In the meantime do not install/uninstall any programs or Windows Updates.

Great and your welcome.

Follow the instructions below to cleanup the tools and logfiles used in this thread.
Rename the file FRST64.exe to uninstall.exe and run it. This will remove all files and folders created by FRST and the tool itself.
Reboot the machine to complete.
You may remove all other tools and log files.

Take care.
