Hello @Harry Flatters,

One other thing that would clarify the above with regard to it being related to Startup . . .
 Autoruns for Windows

Autoruns allows you to Disable problem Startup items.

> Website => Autoruns for Windows - Docs.Microsoft
> Direct Download => Autoruns for Windows - SysInternals

I hope this helps!

I will certainly download this for future startup problems - thanks

Hi Harry, this is a video tutorial on using Autoruns that I found useful.

Advanced Autoruns Tutorial - How to disable programs that start with Windows - YouTube

BTW, I downloaded the entire SysInternals Suite which includes Autoruns and many other useful tools.
