Boot Camp Error Code 0xc0000225 after Windows crashed

Hi All

I recently had an issue with Windows on Bootcamp, with the following displaying when I try to log in through Bootcamp:

Windows 10 had crashed on an update. I was able to re-install Windows, and it's now working fine if I reboot and open up on the Windows drive.

I know there was another question posted recently 'Boot Camp Error Code 0xc0000225', (17-Feb-2020) but I need to keep Windows to run other programs, and I'm not too tech-minded.

I'm not sure if I need to create 'installation media', as directed on the Microsoft website, and if I do, do I create it on the MacBook side or the Windows side? (sorry, did I mention I'm not tech-minded!)

Can anyone help with simple instructions 🤓

Thanks in advance!
