Hi Balakrishnan,

Thank you for posting your query on Microsoft Community.

I understand that the Start menu is missing from the desktop. We will assist you to resolve the issue.

This issue may arise when some of the Windows components gets corrupted.

I suggest you to perform SFC scan and check if it helps.
 
System File Checker (SFC) is a utility in Microsoft Windows that allows users to scan for and restore corruptions in Windows system files. Perform System File Check (SFC), and then check if this fixes the issue.

1. Press the Windows button + Ron your keyboard, and type cmd.
2. Choose Command Prompt (Admin). You must run the command prompt in Administrator level.
3. On the command prompt type sfc /scannow and hit enter.
4. If everything went okay and no errors were found, restart your computer and see if the issue re-occurs.

If the issue persists, I suggest you to perform DISM from the below link.

The DISM or System Update Readiness tool may help you to fix some Windows corruption errors.
