Quick Fixes to Try

Prior to delving into the more specific solutions suggested below, consider giving these easy fixes a shot initially to determine whether they can effectively resolve the issue.

• Reboot your system: the first and obvious thing you should do when you face any sort of problem on your system is restart it. Sometimes, it’s all you need to quickly resolve any small glitches that have caused your computer to misbehave, including the Action Center not opening.

• Fix corrupted and broken system files: if the Action Center isn’t popping up because some of your system files are corrupt or broken, firing up the SFC can quickly provide help.
• Use a system restore point: a good habit that all Windows users need to get into is regularly creating system restore points. If you have one from before the Action Center stopped opening, taking advantage of the system restore point now can get the Action Center to open again.

1. Restart Windows Explorer

If the above generic fixes didn’t solve your issue, restarting Windows Explorer in Task Manager can help unlock any locked files that may be causing the Action Center issue.

1. Right-click an empty part of the taskbar, and select “Task Manager.”

2. Select the “Windows Explorer” process in the “Processes” tab, and click “Restart task.”

3. Windows Explorer will restart, and the Action Center should reappear.

2. Re-Register Action Center via PowerShell

If the Action Center is still not opening after restarting Windows Explorer, try re-registering the Action Center.

1. Press Win + X, and select “Terminal (Admin)” or “Windows PowerShell (Admin).”

2. Copy and paste the following command into PowerShell, and press Enter.

Get-AppxPackage | % { Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml" -verbose }

3. Restart your Windows Computer, then check whether you can open the Action Center.

3. Perform a Clean Boot

The reason you can’t open Action Center could be that there’s a software conflict. A good way to isolate the offender is to boot Windows with minimal apps, programs, and drivers running. Put your computer in a clean boot by following the steps below:

1. Open a Run dialog by pressing Win + R, then enter msconfig in the text box, and click “OK.”

2. In System Configuration, select the “Services” tab, tick the “Hide all Microsoft services” checkbox, and click “Disable all.”

3. Click “Apply” but don’t close “System Configuration” just yet.

4. Select the “Startup” tab, and click “Open Task Manager.” This will open Task Manager with the “Startup” tab selected.

5. Check the “Status” column for each item, and if it says “Enabled,” select the item, then click “Disable.” Do this until you’ve disabled everything.

6. Click “OK” to close “System Configuration,” then close Task Manager as well.

7. Once you restart your computer, you will have performed a clean boot. Check whether you can open the Action Center. If you can, it means that one of the items you disabled is the culprit. Launch or enable them one by one to find the offender.

4. Enable Action Center

If you can’t get the Action Center to open, even after re-registering it, then perhaps someone or something disabled it without your knowledge. To fix that, you just need to enable it again. You can do that in the Local Group Policy Editor or Registry Editor.

Tip: Windows Home users need to activate the Group Policy Editor first.

In the Local Group Policy Editor

1. Open a Run window, enter gpedit.msc in the text box, then click “OK.”

2. Navigate to “User Configuration -> Administrative Templates -> Start Menu and Taskbar.”

3. Double-click the “Remove Quick Settings” policy in the right panel on Windows 11 or the “Remove Notifications and Action Center” policy in the right panel on Windows 10.

4. Set the radio button to “Not Configured,” and click “OK.”

In the Registry Editor

One important thing to keep in mind is that making a mistake in the Registry Editor can mess up the Windows registry. To make sure that you can roll back detrimental changes, we highly recommend creating a backup of the Windows registry before you proceed.

1. Open Windows Run, enter regedit in the text box, and click “OK.”

2. Navigate to “HKEY_CURRENT_USER -> Software -> Policies -> Microsoft -> Windows -> Explorer.”

3. Right-click the “Explorer” key on the left panel, and select “New -> DWORD (32-bit) Value.”

4. Name the value you just created “DisableNotificationCenter,” then double-click it to edit it.

5. Set “Value data” to “1,” and press “OK.”

6. Restart your computer for the changes to take effect.

5. Rename UsrClass.dat File

If the above method doesn’t resolve the problem, try renaming or deleting the “UsrClass.dat” file. This is where Windows stores all of the user profile information.

1. Press Win + R, copy and paste %localappdata%\Microsoft\Windows in the text box, and click “OK.”

2. By default, Windows hides the “UsrClass.dat” file. To make it visible in Windows 11, click “View,” and select “Show -> Hidden items.” In Windows 10, select the “View” tab, then tick the “Hidden items” checkbox.

3. Select the “UsrClass.dat” file, press F2, and rename it “UsrClass.dat.bak.” If you receive a warning message when trying to change the file extension, click “Yes” to continue.

4. Sometimes the “UsrClass.dat” file will be in use, and you will not be able to rename or delete it.

5. You will need to log in to another user account, and try to change it from there.
6. If you don’t have another user account, enable the Super Admin account, and use that instead. If you already have a second user account, log in to that.

7. Press Win + E to open File Explorer, and head to “This PC -> Local Disk (C:) -> Users -> <username> -> AppData -> Local -> Microsoft -> Windows.” Be sure to replace “<username>” with the username of your original account.

8. Try to rename “UsrClass.dat” to “UsrClass.dat.bak.” Since the file is no longer in use by the previous user account, you should be able to rename it without issue.

9. After renaming the file, restart your system, and see whether the Action Center is working.

If it isn’t working after trying all the steps in this guide, you may need to reset your Windows computer. Before you do, learn how to reset Windows without losing data.
