If you RESTART Windows, not Shut Down just restarting, does it take such long time to Boot?

no if I do a restart normally or update it starts in 1 -2 mins, its only overnight, and in the morning it takes 10 to 20 mins

OK. Probably you have a Hardware issue.

You could Test Memory modules : Open an elevated Command Prompt and Type - mdsched.exe and press enter.
Restart
Windows Memory Test will start automatically

Try to swap memory modules, or change to other slots , or put it as "Single-Channel".

Well, If you have CPU/Memory/Graphics Overclocked, then put it to "Normal".
Remove / Disconnect all not strictly necessary Cards/Drives from Motherboard and see it the issue persists.

Just as a random thought, what USB devices are plugged in?

hi, I don't have anything overclocked, all that is connected to the mainboard is a mouse keyboard, printer, second hard drive, which I have disconnected before and speakers, plus a modem, but nothing else, all usb, that's it, so I don't know what to do now, apart from reinstall windows 10, which I don't what to do really, thanks john

OK.
USB Drives could cause Windows to take a long time "searching" for it.
EDIT: I recall , a internal 56K Modem Card was causing me such a problem, many years ago.

You may want to do a Windows Repair , with a In-Place Upgrade, it will not delete anything, your Files/Doc/Software will stay as it is.
Look in this tutorial how to do it :
