Restart problem.

[Den]

Whenever I upgrade anything Windows 10 or even iTunes etc' and it tells me to restart the computer, it goes into a endless cycle of black screen and the twirl thing at the bottom. At first I have the Windows flag showing but once that turns off it can run for hours. I have tried everything I can find on the net but to no avail.
If I leave it and try again later (sometimes after unplugging the power) it will load up eventually.

Any thought or should I just turn the computer off instead of restart and then turn it back on later?

I think you just have to be patient Den.  But I have to say it's very disconcerting.

I think it's a feature. I have the same problem with two PCs. My main PC often won't reboot even from a cold start so I never turn it off and I dread updates. My best guess is Windows 10 is not fully comparable with older hardware.

I've read about this "black screen of death" and it has happened to me on the odd occasion, but seemed to fix itself. A common fix is to disable fast startup.
I know it sounds backwards to disable fast startup to stop it being slow to start up but there is a kind on perverse logic to it if you Google "disable fast startup windows 10".
Its only a switch so I'd give it a try. Let us know how you get on.
If that fails, don't forget, as a new feature of Windows 10 there is a "Contact Support" on the start menu and you will get to M/Soft. Worth a try if the fast boot does not help.

It is not fully compatible with it's self.

I'm not having any problems, or have I spoken too soon?!
