Task Manager Disabled By Administrator on Windows? 5 Ways to Fix It

Task Manager Disabled Admin

Every now and then, you may need Task Manager to, for example, end a task that's hogging system resources or stop a process you don't want running in the background. But if trying to open this tool produces a message saying that "Task Manager has been disabled by your administrator," it can be confusing. It could be that the administrator has really disabled it. If not, it could be the work of a virus. This guide shows you various ways to fix the problem.

Good to know: need to open the Task Manager quickly in Windows? We demonstrate how to fire it up.

1. Reach Out to the Administrator

Before you tweak anything on your Windows PC, we recommend contacting the network administrator first if you don't have administrator privileges or know the username and password. Ask why they've disabled Task Manager and whether they can enable it again.

If the administrator is unresponsive or doesn't recall disabling Task Manager, try the solutions below.

2. Scan Your PC for Viruses

If the administrator did not disable Task Manager, then it's quite likely that a virus made the change. To confirm this theory, a virus scan is in order.

Easily carry this out by using Microsoft Defender from Command Prompt and running a full scan. You can also use a third-party antivirus program to perform the scan, but bear in mind that Microsoft Defender is a competent antivirus that does a good job of removing viruses from PCs, so installing another antivirus isn't really necessary.

Once you're sure your computer is virus-free, check to see whether the error message no longer appears as you try accessing Task Manager.

Tip: if you still want to install a third-party antivirus, check out the best free options available.

3. Enable Task Manager Using Command Prompt

You may be getting the "Task Manager has been disabled by your administrator" message because Task Manager has been disabled. One of the easiest ways to enable Task Manager is through Command Prompt, but you need to launch it as an administrator.

  1. To do that, press Win + S to bring up Windows Search and type cmd in the search box.
  2. Click "Run as administrator" in the right pane of the search results.
