UCCNC shuts down unexpectedly

Well xp works FAULTLESS with Mach3. The machine is dedicated to it's cnc purpose so if it isn't broke don't fix it.

Of course, I never said you should change anything you are happy with. That was not the subject at all.

Have you ever had a win update destroy your pc?.
I have and it's a b*******d.

Never had any PC destroyed because of an update. I think your conclusion of blaming Microsoft for that is not based on facts, but something else.

It's only Microsoft that cocks things like updates up. They generally don't test them properly before release.

That's just pure nonsense. Microsoft is more serious than you can ever imagine. They don't release ANYTHING which is not tested. It is clear however that you don't work in software development business area and hate Microsoft, but I could not care less. In every camp (Linux, Ios and Windows) there are some haters, but none are fact based, just emotions. Some people are like that and there is nothing to do about them, other than feeling sorry for them.
