hi simon, welcome in community
i’m Alvise, an independent consultant and I can understand your concern and, please, don't worry I am here to help you
proceed in this way, press the WIN + X buttons and open terminal (admin), now type
net stop bits
net stop wuauserv
net stop cryptsvc
ren %systemroot%\System32\Catroot2 oldcatroot2
net start cryptsvc
del /f /q %windir%\WindowsUpdate.log
del /f /s /q %windir%\SoftwareDistribution\*.*
net start bits
net start wuauserv
after each command press enter
if you want you can create a text file from notepad, save it as All files type and give it a .bat extension
then run it as administrator
after doing so, try again with the updates
let me know how it goes
Elvis
