4 Fixes for Taskbar Calendar Not Opening on Windows 11

Quick Tips

• Run the SFC and DISM scans to fix issues caused by corrupt or damaged system files.
• Re-registering your apps using PowerShell can also help get the taskbar calendar working again.
• If nothing else works, consider creating a new user account in Windows.

Try Basic Fixes

• Restart the Windows Explorer process: If the Windows Explorer process is malfunctioning on your system, the taskbar may not load correctly, and you may have trouble opening the calendar. To fix it, press Ctrl + Shift + Esc to open the Task Manager. In the Processes tab, locate the Windows Explorer entry. Right-click on it and select Restart.
• Install Windows updates: If the issue is occurring due to a bug, installing pending updates should help fix it. Press the Windows key + I to open the Settings app. Switch to the Windows Update tab and click the Check for updates button to download and install updates.

Fix 1: Expand the Taskbar Calendar

Before you try anything else, it’s a good idea to ensure you haven’t accidentally collapsed the taskbar calendar. If you have, the taskbar calendar will display only the current day and date.

To open the monthly calendar view, click the clock icon on your taskbar and then click the up arrow next to the current date.

Once the calendar expands, you should see the full monthly view.

Fix 2: Run SFC and DISM Scans

Corrupted or missing system files on your computer can also cause the taskbar to misbehave. If that’s the case, running the SFC (System File Checker) and DISM (Deployment Image Servicing and Management) scans should help. Here’s how to run them.

Step 1: Right-click the Start icon and select Terminal (Admin) from the list.

Step 2: Type the following command in the console and press Enter.

SFC /scannow

Step 3: Type the following commands individually and press Enter after each to run the DISM scan.

DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

This may take a while, so be patient. After the scan is complete, restart your PC and check if the taskbar calendar opens as expected.

Fix 3: Re-Register All Apps Using PowerShell

Another thing you can do to fix issues with the taskbar calendar is to re-register the system apps on your Windows 11 PC. Don’t worry; it isn’t as complicated as it might sound and only requires running a single command.

To re-register system apps on Windows:

Step 1: Click the search icon on the taskbar, type in powershell, and select Run as Administrator.

Step 2: In the console, type the command given below and press Enter.

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)AppXManifest.xml"}

Restart your PC after this and check if the issue still persists.

Fix 4: Create a New User Account

If all else fails, it’s likely that some of the critical files associated with your user account have become corrupted. In that case, your best option is to create and switch to another user account on Windows. Here’s how you can go about it.

Step 1: Press the Windows key + I to launch the Settings app. Swtich to the Accounts tab and click on Other users.

Step 2: Click the Add account button.

Step 3: Type in your email address and follow the on-screen instructions to create a new user account on Windows.

Sign in with the newly created user account and check if the issue is still there.
