Missing icons for Trusted Microsoft Store Apps in Start Menu search and taskbar

Below are some troubleshooting steps in ascending order of severity.
Before starting, take careful backups including a system image.
I suggest using for that
AOMEI Backupper Standard Free.
Create also the AOMEI boot CD or USB and test that it can boot and can see
both your system disk and the disk where the image backup is stored.

To reinstall all Store apps for the current account :

1. Open Windows PowerShell as Administrator
   
2. Copy and paste the command below in PowerShell, and press Enter
   
   
3. Wait for this to finish and reboot.
   

If this does not work, Windows is in bad shape.
Start by checking the integrity of system files :

1. Open an elevated Command Prompt (cmd) or an elevated Windows PowerShell.
   
2. In the elevated command prompt, execute the command below :
   
   
3. Reboot
   

If this does not help, follow the steps outlined in the article
