Windows 10: my pc is not showing a shutdown option

My pc takes for ever to shut down when i restart

Suggest cleaning up your startup list .There may be many services / Apps you can remove on startup which is not needed on boot or during shutdown.
Before you shutdown the Pc check what is running in Task Manager as a program or service in not killing the process on shutdown

Would suggest cleaning up running apps and services -Autoruns, StartupMonitor,HighjackThis,
Malware Scan - Malwarebytes,ADWcleaner, Combofix

Hi,

The issue that you've encountered regarding the shutdown behavior of your PC is may be caused by some settings or program conflicts. To sort out your concern, we suggest that you manage the
Shutdown settings from the Control Panel. To do this, you may follow the steps below:

• Click Start, type Control Panel, and then press
  Enter.
• On the Control Panel search box, type Power Options and select it from the search results.
• Click Choose what the power buttons do.

  Change settings that are currently unavailable to make it enable.
• Uncheck Turn on fast startup (recommended) and then click
  Save changes.
• Once you’re done, you may check if the issue persists.

PC is Suffering Unexpected Shutdowns

Most important detail to me would be whether these shutdowns are sudden, in which case it's likely a short or PSU issue (capacitor aging maybe?) or graceful windows style shutdowns, which suggests software interference.

It could also be overheating components if it's a sudden shutdown. What are your thermals like?
