Further to my last question:
https://www.theanswerbank.co.uk/Technology/Computers/Question1588036.html
.... I've been in touch with Microsoft and they've advised me to do a system restore.
However, when I try and perform the restore, I get the following error message:

I tried turning my anti-virus programme off (Defender), but I still get the same error message.
Also, the earliest point I can go back, probably isn't far enough back - is there a way to go back further?? I've clicked the box to show more restore points, but it doesn't go back far enough.
Failing this, I'm considering resetting my laptop. I know it's drastic, but it's a last resort ad I want this sorting now 'cos it's bugging me.
Just how drastic is a reset?? Will I need a Windows disc, as I don't have one and will it keep all my personal files/folders, etc. I don't mind losing all the programmes that I've installed along the way, as I keep a note of what I've installed, so it should be fairly straightforward!!!!
Thanks again for any help :)
