Why is my start button not working?

Hello,

I understand your inconvenience with accessing Start button, icons on Taskbar in Windows 10, we well help you with this issue.

This issue might be due to corrupted or missing System files.

I suggest you to perform the below troubleshooting steps and check.

Method 1: Run the SFC.

System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.

Follow the below steps:

• 
  Right click on the Start button, click on
  Command Prompt (Admin).
  
• 
  Type “sfc /scannow” without the quotes and hit
  Enter.
  
• 
  After the scan, restart the computer and check for the issue.
  

Method 2: Run the DISM Tool.

If the issue persists, I would have you run the DISM tool to check the system health and will try to restore the files.

• 
  Right click on the Start button, click on
  Command Prompt (Admin).
  
• 
  In the Administrator: Command Prompt window, type the following commands. Press the
  Enter key after each command:
  

• 
  DISM.exe /Online /Cleanup-image /Scanhealth
  
  
• 
  DISM.exe /Online /Cleanup-image /Restorehealth
  

3. To close the Administrator: Command Prompt window, type
Exit, and then press Enter.
Note: The tool might take 15-20 minutes to finish running, so please do not cancel it.

I suggest you to refer to the below Microsoft article, try the troubleshooting steps mentioned and check if it helps.
