Starting applications as administrator takes a long time

Question

_{Wednesday, June 29, 2016 1:50 PM}

It's very slow to open Task Manager (by rightclicking Taskbar and choosing Task Manager), Command Prompt (rightclicking the Windows icon on the Taskbar and choosing "Command Prompt (Admin)", or other applications that require administrator privileges. It takes around 10 seconds from I start the application to something appearing on the screen. The system is fully responsive while it is opening, so I'm never quite sure if the application has crashed or it will open.

The PC is very recently cleaned (reformatted and reinstalled) and is connected to a domain.
Restarting the computer has no effect.
Having no other applications open has no effect.
No antivirus running.

Why is it so slow to open these applications?

After our IT department made some changes to our network (new firewall, restored access to some network drives) opening applications as administrator is now quick again.

It would seem like Windows is checking some permissions against a server (domain controller?) when opening applications like this. I'm surprised it has to do that when it should be enough to check local permissions.

Hi Glenn,

"The PC is very recently cleaned (reformatted and reinstalled) and is connected to a domain."
When did this issue start to occur? Did it occur immediately after installing?
Were there any error message recorded in Event View when this issue occurred?
When you open Task Manager, is there any process and applications taking too much resources?
What is the exact machine model?
Before we install Windows 10, we need ensure the device manufacturer website has released the Windows 10 compatible driver for your model machine.

Here are some general solutions we could try at least.
Run "dism /online /cleanup-image /restorehealth" to scan and restore the system components to have a check at first.
Install the last version of drivers from manufacturer website.
In addition, we could also boot into clean boot environment to open Task Manager and Command Prompt again to check if it caused some third party applications and services.
