I still find myself slipping back to Comodo, Firefox Thunderbird combo. So decided to do some analysis. Thunderbird is compatible with H_C so that's fine as I prefer that for emails. Just faster and more secure than Windows 10. I think it's down to Edge bing search I'm not a fan of so I guess I should experiment with changing that.
The other thing is some slow system at times but not sure if that's down to system updates or running WD in it's own sandbox. It's probably fine for newer machines but at the end of the day I have an old laptop with a 4th generation i3 chip. I just can't afford a upgrade at the moment and what I would get around the £400-500 price mark isn't a great deal better than what I have. /Shrug, maybe after Christmas.
So more tweaking to be done and try WD again without running in it's own sandbox.
