Reset Task Manager to Default Settings in Windows 11

To reset Task Manager to its default settings in Windows 11, open Task Manager, click the gear icon (Settings) in the bottom-left corner, then click the “Restore default settings” button at the bottom of that page. This immediately clears all customizations you have made, such as hidden columns, changed sorting, or non-default performance graph views, returning the app to its out-of-the-box state.

What Actually Gets Reset

Task Manager in Windows 11 stores its preferences in a small configuration file on your user account. When you click “Restore default settings,” it deletes that file and recreates it with the default values. Specifically, it resets:

• Which columns are visible in the Processes, Performance, App history, Startup, Users, and Details tabs.
• The width and order of those columns.
• Which tab was last selected (it will open to Processes by default).
• Any changes you made to the Performance tab’s graph view (e.g., switching from the default CPU graph to a per-core view).
• Whether the “Efficiency mode” column is shown or hidden.
• Any filter or search terms you had typed in the search box (they are cleared).

It does not reset system-wide settings like which processes run at startup, change power plans, or alter any Windows services. It only affects Task Manager’s own interface preferences.

Why You Might Need to Reset

There are a few common situations where resetting is the right fix:

• Accidental changes: You hid a column you need, or dragged a column to a weird position and cannot get it back.
• Display glitches: Sometimes after a Windows update, Task Manager’s saved state gets corrupted, causing it to show blank areas, missing text, or a frozen UI.
• Performance tab confusion: You changed the CPU graph to show logical processors, and now it is a cluttered mess of tiny graphs.
• After a profile corruption: If your user profile is partially damaged, Task Manager might fail to save changes; resetting can clear the bad state.

If you are troubleshooting Task Manager not opening at all, a reset won’t help because you cannot get into the Settings page. In that case, you would need to delete the configuration file manually (see the FAQ section) or run the System File Checker.

Step-by-Step Reset Instructions

Here is exactly how to do it, with the menu names as they appear in Windows 11 (version 22H2 and later):

1. Press Ctrl + Shift + Esc to open Task Manager. Alternatively, right-click the Start button and select “Task Manager” from the menu.
2. If Task Manager opens in “compact mode” (just a small window with a list of apps), click “More details” at the bottom to expand it to full view.
3. Look at the left sidebar. You will see icons for Processes, Performance, App history, Startup, Users, Details, and Services. At the very bottom of that sidebar, click the gear icon (labeled “Settings”).
4. The Settings page opens. Scroll down to the bottom. Under the “Task Manager” heading, you will see a button labeled “Restore default settings”.
5. Click that button. A confirmation dialog may appear asking if you are sure. Click “Restore” or “Yes” to confirm.
6. Task Manager will immediately revert to its default layout. You can close and reopen it to confirm the changes stuck.

That is all there is to it. There is no need to restart Windows or sign out.

What If the Button Is Grayed Out or Missing?

In rare cases, the “Restore default settings” button might be grayed out or not appear at all. This usually happens when:

• You are running Task Manager with limited permissions (e.g., as a standard user on a work PC where Group Policy disables the setting).
• The Task Manager configuration file is corrupted so severely that the app cannot even render the button properly.
• You are using an older Windows 11 build (before 22H2) where the Settings page had a different layout. In that older version, the button was still there, but under a slightly different heading.

If the button is unresponsive, the manual fallback is to delete the configuration file. Here is how:

1. Close Task Manager completely.
2. Open File Explorer and navigate to: %LocalAppData%\Microsoft\Windows\TaskManager (you can paste this into the address bar).
3. You will see a file named TaskManager.xml. Right-click it and choose “Delete”.
4. Reopen Task Manager. It will recreate the file with default settings.

This manual method works even when the in-app button fails, and it is the same thing the button does under the hood.

Common Misconception: Resetting vs. Ending Tasks

A frequent confusion is that “resetting Task Manager” means restoring the list of running processes or clearing the Startup list. That is not what it does. The Startup tab in Task Manager shows programs that launch when you log in. Resetting Task Manager’s settings will not disable or re-enable any of those startup items. It only resets the app’s own view preferences. If you want to change which programs start automatically, you do that in the Startup tab itself (right-click an item and choose Enable or Disable).

Similarly, resetting does not kill any currently running processes. It does not end tasks, force quit apps, or change how Task Manager behaves when you click “End task”. It is purely a UI preference reset.

How to Prevent Future Accidental Changes

If you keep accidentally hiding columns or messing up the layout, there is no built-in “lock” feature in Task Manager. However, you can minimize the risk by:

• Not right-clicking column headers unless you intend to change them. The context menu for columns is right there, and it is easy to toggle a checkbox without noticing.
• Using the search box at the top of the Processes tab instead of filtering by clicking column headers. The search box is temporary and does not alter the saved layout.
• If you work on a shared PC, consider creating a separate Windows user account for other people. Task Manager settings are per-user, so your layout stays intact.

Frequently Asked Questions

Will resetting Task Manager affect my startup programs?

No. The Startup tab’s list of enabled/disabled programs is stored separately in the Windows registry and in the Startup folder. Resetting Task Manager’s settings does not touch that list. Your startup programs will remain exactly as they were.

Can I reset Task Manager without opening it?

Yes, if Task Manager is completely broken and won’t open, you can delete the TaskManager.xml file manually as described above. Navigate to %LocalAppData%\Microsoft\Windows\TaskManager in File Explorer, delete the file, and then try opening Task Manager again. It will recreate the file with defaults.

Does resetting Task Manager clear my performance history graphs?

No. The performance graphs in the Performance tab show real-time data since the last boot. They do not store long-term history. Resetting the settings only affects how the graphs are displayed (e.g., which CPU view you see), not the data itself. The graphs will continue to show current activity.

Why did Task Manager change on its own?

Windows updates occasionally change default settings or reset certain UI preferences if the update detects a corrupted configuration. Also, if you signed in with a different Microsoft account or after a profile repair, Task Manager might load a fresh default state. It is not a bug you need to fix; just reapply your preferences.

Is there a command-line way to reset Task Manager?

There is no official command-line switch for Task Manager that resets its settings. The only reliable command-line approach is to delete the configuration file using a command like del "%LocalAppData%\Microsoft\Windows\TaskManager\TaskManager.xml" in an elevated Command Prompt or PowerShell. That achieves the same result.

Will resetting Task Manager remove the “Efficiency mode” feature?

No. Efficiency mode is a built-in feature of Windows 11, not a customizable option that can be turned off by resetting. Resetting only shows or hides the column that displays which processes are in efficiency mode. The feature itself remains available.
