Question

When the task manager is started as a common domain user, the UAC pop-up window is triggered. After you enter the current user name and password, the UAC pop-up window can be opened.

Why do some machines have this prompt, and some machines open the task manager directly?

In the same OU, the domain policy and system are the same.

In the system32 directory, you see taskmgr.exe with UAC shield.On a normal computer, there's no UAC shield.
