Open cmd.exe with Run as Administrator. Run:

1. SFC /SCANNOW and allow to complete.
2. dism.exe /online /cleanup-image /restorehealth

Restart after the above and test.

Are you able to get a look at your Windows Event Logs?

1.Right click on the Start button and select Control Panel > System & Security and double-click Administrative tools
2.Double-click Event Viewer
3.Select the type of logs that you wish to review (ex: Application, System, Windows)

NOTE: To access the Application Logs once in Event Viewer, go to Windows Logs > Application, for shutdown errors refer to Application and System logs.

What kind of errors are popping up in the Windows event log under System? usually you'll see red or yellow ! for errors and warnings.
Sometimes they might tell you what might be going on here.

System may be over heating as well if it hasn't been cleaned recently.  Dust build up inside the system etc.

If DISM will not run, you may need to run a Windows 10 Repair Install from the Windows 10 media creation link.

dont have that.  this is a work computer imaged by desktop support in a different state.

Are you saying you dont know how to edit the cmd?  "The Online option has been duplicated on the command-line.
Remove the duplicate option and try the command again."
JohnBusiness Consultant (Owner)Commented:
Something in DISM has been damaged. Can your Office reload a new image. That would be best here.
Jane UpdegraffSr. Systems AdministratorCommented:
You have the /online switch typed twice in your command "C:\WINDOWS\system32>dism.exe /online /cleanup-image /restorehealthdism.exe /online /cleanup-image /restorehealth"

i would first try removing one of the duplicates and see if DISM loads.
CompProbSolvCommented:
Instead of: dism.exe /online /cleanup-image /restorehealthdism.exe /online /cleanup-image /restorehealth
use:
dism.exe /online /cleanup-image /restorehealth
JohnBusiness Consultant (Owner)Commented:
Probably a typo in the author's post.

"dism.exe /online /cleanup-image /restorehealth"  was in my first post above and did not work
Jane UpdegraffSr. Systems AdministratorCommented:
yup agreed probably a typo.

Task manager might be missing something that it needs in order to run, for instance if a critical DLL is missing or corrupted. It would be faster to just load a new image onto the box rather than try to figure out what's wrong with it if that's the case. So I would get hold of your systems administrator and get them to reload or replace the PC.

Also, are you sure that you have local administrative rights? If you do not have admin rights and UAC is turned on (which in Windows 10 it almost certainly is) and your UAC window is not popping up asking you to login as a local administrator to open Task Manager, it might be that you don't have rights to open it and what's hanging up isn't task manager but the UAC prompt window.

Why are you trying to open task manager anyhow if you are an end user and not an admin? Not saying it's bad, just wondering.
JohnBusiness Consultant (Owner)Commented:
End users can open task manager.

Mark - it is possible (but I think unlikely) that the UAC prompt could be hidden. Did you check this.  Easy - make sure nothing is open, right click on the Task Bar and select Task Manager.

What happens?

Jane Updegraff, yes we are Admins on our boxes
JohnBusiness Consultant (Owner)Commented:
You need to restart after running DISM  (preferable at least).
Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
Nothing's worked so far.  Still hangs when open Task Mgr.
JohnBusiness Consultant (Owner)Commented:
Please get your work office to reload the Windows image
Zaheer IqbalTechnical Assurance & ImplementationCommented:
What antivirus do you use ?
try disabling it .
Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
Symantec.  And there's TONS of errors from it in EV.  We cant disable it; we're on a domain.
JohnBusiness Consultant (Owner)Commented:
We have Symantec Endpoint on all our Client Machines. That does not cause any issue with Task Manager.

I really suggest rebuilding your machine.
Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
The computer will NOT be reimaged
JohnBusiness Consultant (Owner)Commented:
With all those errors, why?

Normal repairs have not fixed the issues.  So Repair Install is much in order. But you say no because Work Machine. Get them to fix it.
web_trackerComputer Service TechnicianCommented:
Back up the user data and as John says reimage it.... call your help desk there seesm to be too many problems with the system and needs to be backed up then reimaged
Zaheer IqbalTechnical Assurance & ImplementationCommented:
next step is to do a hardware test should as disk and memory.

we need eliminate what could causing the issue. So I suggest you work with your IT department and try to narrow down the issue.

surely as a test you can uninstall Symantec Endpoint protection or disable.

You have work on a trial and error basis.
if you going spend hours trying to diagnose and issue which only affects one machine then the easiest thing would be to re-image.

I would update the BIOS and Chooser drivers and any driver that can be updated from the vendor.
Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
This is a new zbook and it's totally updated.  I worked with HP on that.  I opened a ticket with my dtp and we'll see what they say too.
Shaun VermaakTechnical SpecialistCommented:
For the time being use Process Explorer as a replacement (it has the option to replace the task manager)
https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer

It is a common action for malware to replace/inject themselves into Explorer, task manager etc.
Sometimes AV blocks it, sometimes AV removes the EXE completely.
Zaheer IqbalTechnical Assurance & ImplementationCommented:
Do you have anymore of the same model that don't have this issue ?

Do you use Dock ?
Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
Desktop Bomgared in and did nothing and suddenly it's not hanging up.  No idea
Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
I use process hacker, Process Explorer
Zaheer IqbalTechnical Assurance & ImplementationCommented:
Do you have the full specs for the machine ?
make model does. it have sad ?
Zaheer IqbalTechnical Assurance & ImplementationCommented:
So are we saying issue has gone away ?
Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
so far it has, yes.  Looks like self-resolution at this point, unless DTP and NW did some tweaking on DeepInstinct
Mark O'BrienDispatch Software Support and Server AdministrationAuthor Commented:
Thank you everyone.  This seems to have self-resolved, but I have zero idea why.
