Hello, and welcome to the Seven Forums!
Well done for researching, and doing what you could by yourself
Please create a new folder on your Desktop called
LOGS.
Copy into that new folder the
C:\Windows\Logs\CBS folder, and the
C:\Windows\WindowsUpdate.log file.
Right click on your new
LOGS folder > Send to > Compressed (Zipped) folder, and upload it here for me.
Thanks a lot!
Richard
