One day, something strange happened on my PC.
At the bottom-right corner of the screen—where the clock, calendar, speaker, and Wi-Fi icons are located—nothing responded when I clicked.
In fact, I realized I can’t open clock or calendar in Windows 11 from the taskbar.
-
The calendar didn’t open when clicking the time
-
Volume control didn’t appear when clicking the speaker icon
-
Wi-Fi settings couldn’t be accessed
I was really confused. I even tried rebooting and using a different mouse, but the issue persisted.
Why Clock, Calendar, and System Tray Icons Stop Working – App Configuration Corruption
This issue isn’t just a temporary glitch — it’s usually caused by corruption in the internal Windows app configuration.
These components on the taskbar (calendar, speaker, network icons) are actually built on UWP (Universal Windows Platform) apps.
When these get corrupted, the icons may appear visually but won’t respond to clicks.
Fix – Recover Windows Apps Using PowerShell
Thankfully, this issue can be solved with a single PowerShell command—no complicated steps involved.
I followed the method below and fixed the issue immediately. Try it out yourself.
1️⃣ Open PowerShell as Administrator
- Click the Search icon (magnifying glass) in the Windows taskbar.
- Type powershell into the search box.
- Right-click on Windows PowerShell in the results and select “Run as administrator”.

2️⃣ Copy and Paste the Command Below
When PowerShell opens, copy the entire command below with Ctrl + C and paste it into the PowerShell window using Ctrl + V.
