Hi all,
I write this with some trepidation as I am, by no means, a computer wiz. I had to do a reset on my laptop, some time ago, which was succesfull. When I next ran a security scan, full, it seemed to take hours. The reason for this was that the old version of W10 was lodged in the Temporary files and needed to be removed to free up memory. I seem to recall reading that it may be done automatically after 10 days? I searched the Microsoft Windows forum to see how to do the removal. It's quite straightforward so long as you take care which boxes you check.
