I was running XP and agree that it was a good OS. However, i had the opportunity to put in a windows 10 machine and because my observatory is connected to the internet and a lot of the software is no longer supported i felt i needed to change. It was done knowing that there would be a degree of hassle, just didn’t realise how much. I would also point out that some of the issue is probably me.
BTW i also live in Essex now at Burnham on Crouch, a lovely part of the world : )
