Sorry to have taken a long time to get back to you.
As I had the problem mentioned I thought that I'd restore the computer to an earlier restore date but that went south very quickly....
Thanks again everyone who took the time to respond, it is appreciated.
Depending on the specs of your laptop, you could have a look at some of the free backup/imaging programs to help restore a laptop back to a known condition very quickly.
I have used 'Macrium Reflect Free' for a long time (but sadly no longer free from Jan 2024)
and am now evaluating 'Paragon Backup & Recovery Community Edition' (currently free) as a replacement
With a USB3 connection on the laptop, and backing up to a USB3 external hard drive, the entire laptop can be restored to a basic build of Windows from an image in about 5 to 10 minutes (via a bootable USB pen drive).
I often make an image before any major computer hardware/software changes so that if the changes go wrong I can go back to the previous setup very quickly.
