The issue arises when the Start menu of the user does not open/function and upon running the Start menu troubleshooter, the user gets the following message: Microsoft.Windows.ShellExperienceHost and Microsoft.Windows.Cortana applications need to be installed correctly Before proceeding, check if booting your system with the bare minimum or in the safe mode resolves the issue. Following workarounds are reported by users to temporary solve the issue:

Solution 1: Update the BIOS, Drivers, and Windows of Your PC

The incompatibility between the essential system modules (i.e., BIOS, Drivers, and Windows) may cause the issue at hand as these entities are not updated to the latest builds. In this context, updating BIOS, Drivers, and Windows to the latest releases may solve the problem.

Solution 2: Disable/Remove the Conflicting Applications

You may encounter the issue at hand if any of the installed applications is hindering the operation of the essential OS entities. In this case, removing the conflicting applications may solve the problem. As the Start menu is not working, you have to dig deeper to make these instructions work for you. Once the problematic application is found, you may keep it disabled at the system’s start or uninstall it.

If you cannot open the Run command box, then you may execute any one of the following in an Administrator Command Prompt to add the new user account (you may execute it in the Advanced Options in Troubleshoot): If the issue is still there, then you may perform a DISM scan of your PC. If that did not do the trick, then you either perform an In-Place Upgrade or a clean installation of Windows.
