Windows 10 Pro version 1511 10586 Won't Shut Down

Windows Update recently downloaded and installed Windows 10 Pro version 1511 10586 on my HP Elite 8300 CMT desktop. So far, this OS seems to work quite well except it won't shut down when I click Shut Down in the Power menu so I have to press the power button on the front of the CPU for a few seconds. It will shut down, however, in Safe Mode. Anyone else having this problem and is there a fix? I've been told that I'll probably need to do a clean install. Some of the replies on Microsoft support don't appear to have helped those who asked so I thought I'd check here before trying anything else.

hello, and welcome to tenforums , cant say I have experienced this on any of my installs .but I do use a different method than you are using of shutting down , give it a try ,, right click on the desktop and choose New shortcut , type in , slidetoshutdown.exe ,click Ok , save to the desktop ,,double click to shutdown , you can drag it down with the mouse ,or hit the Windows key , also if you wish you can put an icon to the file ,right click on the file and choose properties/change icon ,ok, and pick an icon ,I pick the red one

Thanks for the welcome and the advice, caperjack. I'll try the new shortcut approach and report results.

If I have usb3 external drives plugged in at shutdown then there will be a restart. The event viewer will report an incorrect shut down.
I gave up finding a solution and unplug the externals before shutdown

This desktop shortcut didn't make a difference
C:\Windows\System32\shutdown.exe -s -t 00

Reply to caperjack and Rose W: neither suggestion worked on my system but thank for the advice. I'm baffled by this issue so I'll take it to a local computer shop that's helped me before.

right click on the windows icon,and open admin command prompt and type in and run system file checker ,it could run for as long a 2hrs so let it finish ,,,command is ,, sfc /scannow .........not here is a space between sfc and /

edit to last post , do it like this in order as shown .

, run the commands in the order below one at a time.

Dism.exe /online /Cleanup-Image /StartComponentCleanup

sfc /scannow

Dism /Online /Cleanup-Image /RestoreHealth

sfc /scannow

My looping shut down started with the November 1156 and I did the scannow which did produce the .cpl file (video) replace but the issue continued. An extra usb3 board had been installed so that was suspected and the desktop went back for a thorough testing, inspection. I took the external to be included but I did not take the external hub. All tests were fine.
The feature did return so the solution appeared to be 'just unplug any usb externals'
BUT this morning the desktop was in a 'semi shut down' status- no monitor, power light on, fans running.
The key combo had to be used to get a shut down which resulted in a restart and the white text bios message
Ctrl Alt Delete
Tab 8 times and Enter
Arrow down 3 times and enter

"USB devices over current status"
A 4 port hub was plugged in but nothing was in the plug
Remove the hub, restart and all returned to normal
So something is off with the hub since it was plugged into the original usb3 port -not the recently installed psi board
Perhaps its drivers or there is something off with usb3
At any rate, these shut down/restart actions are commonly posted for Win10 with no easy solutions. It appears to me to be a hardware issue as well as a driver issue. The same hardware operated well in the Win7 environment.

Reply to Rose W: I've unplugged the only USB that I have (not a USB hub) and still no go on the shut down. I'm going to have to refer this issue to a local computer tech shop to find a remedy. Thanks for your input and advice.
