FIX: Windows 10 Calendar app greyed out on the Start menu

3 minute read

Some users have stated on forums that Calendar app tiles, and other apps, are grayed out on their Start menus after Windows 10 updates. When they click the Calendar app tile, a window opens and then closes. This bug is primarily a consequence of the grayed out apps not fully processing the required updates. These are a few resolutions that might fix a Windows 10 Calendar app grayed out on the Start menu.

1. Open the Windows Store App Troubleshooter

There are two troubleshooters that might fix the Calendar app. One is the Windows Store App troubleshooter included with Windows 10. You can open that troubleshooter as follows.

3. Reregister the Microsoft Store

Greyed out apps on the Start menu can be due to corrupted Microsoft Store files. As such, reregistering the MS Store app might fix a Calendar app grayed out on the Start menu. This is how you can reregister the MS Store.

  • First, enter ‘PowerShell’ in the Cortana search box.
  • Right-click Windows PowerShell in Cortana to open its context menu, and select the Run as administrator option.

  • Enter ‘Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)AppXManifest.xml”}’ in the PowerShell window, and press the Return key.

  • Restart your desktop and laptop.
  • After reregistering MS Store, reset the MS Store’s cache. To do that, press the Windows key + R hotkey.
  • Then input ‘wsreset.exe’ in Run, and press the OK button. The Store app might then update the greyed out Calendar app.

4. Reinstall the Calendar App

  • Reinstalling the Calendar app is another probable fix. To uninstall Calendar, open the folder C:Windowssystem32 in File Explorer.
  • Click the File tab and select Open Windows PowerShell > Open Windows Powershell as administrator to open Powershell.

  • Input ‘Get-AppxPackage *windowscommunicationsapps* | Remove-AppxPackage’ in PowerShell and press Enter to uninstall the Mail and Calendar app.
  • To reinstall Mail and Calendar, open this page.

  • Then press the Get the app button to install the app.

5. Update the Graphics Card Driver

Updating the graphics card driver can fix glitchy Start menus after Windows updates. So a video card driver update might also fix grayed out app tiles. This is how you can update the graphics card driver in Windows 10.

  • First, enter ‘dxdiag’ in Run’s open text box and click OK to open the window shown directly below.

  • Note down the operating system and graphics card model details on the System and Display tabs.
  • Next, open your graphics card manufacturer’s website in a browser.
  • Open the driver section of the website.

  • Then select your graphics card model and Windows platform from the site’s drop-down menus. If the site has a driver search box, enter your graphics card model there.
  • Download the most update driver that’s compatible with your 64 or 32-bit platform.
  • Thereafter, open the driver installer from the folder you saved it in to install the graphics card driver.

Those resolutions might fix the Mail and Calendar, and other apps, grayed out on the Start menu. In addition to those fixes, you can also try resetting the Calendar app as covered in this post.
