If after a system update/upgrade and the Start Menu is not working, opening, freezing, or not responding, and you see the StartMenuExperienceHost.exe error with Event ID 1000, 1002 in Event Viewer or logged under Critical events in Reliability Monitor on your Windows 11 or Windows 10 PC, then this post is intended to help you with the most suitable solutions you can apply to resolve the issue.
What is StartMenuExperienceHost.exe?
StartMenuExperienceHost.exe with the friendly name Start is an executable baked into the core OS that manages the Windows 11/10 Start menu. Before Windows 10 v1903, the Start menu was handled by the Windows Shell Experience Host (ShellExperienceHost.exe). Due to instability, for example, if there’s an issue with the Start menu, the whole explorer.exe could crash and need a restart.
So, to improve the Start menu performance, StartMenuExperienceHost.exe was introduced. With this, if the Start menu encounters problems, you will only need to restart the StartMenuExperienceHost.exe process and not the whole system or explorer.exe. the file is located in the %SystemDrive%\Windows\SystemApps\Microsoft.Windows.StartMenuExperienceHost_cw5n1h2txyewy folder

If you’re having Start Menu issues, and you see the StartMenuExperienceHost.exe error 1000, 1002 in Event Viewer or Reliability Monitor on your Windows 11/10 PC, then our recommended solutions presented below are intended to help you resolve any Start Menu issues that are triggering this event on your device.
- Run SFC and DISM scan
- Restart Start Menu
- Re-register the Shell experience
- Re-register twinapi.appcore.dll file
- Uninstall Update or Rollback Upgrade
- Use System Restore Point
- Reset/Reinstall Windows 11/10
Let’s look at the description of the process as it relates to each of the listed solutions.
1] Run SFC and DISM scan
There has been debate concerning which scan to run first, SFC or DISM. Which of the scan goes first depends – you may run the SFC scan first to repair system files, but if you get the following message:
Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.log.
It’s likely the WinSxS folder where SFC pulls files to run a repair is corrupted. So, in this case, you can now run the DISM scan to restore health.
Once you get a clean bill of health after the scan, you can now rerun SFC. Every other thing being equal, the SFC scan should be able to successfully repair any corrupted system files. Otherwise, there could be other underlying issues, and possibly a bad Windows system image.

4] Re-register twinapi.appcore.dll file

So, it could be a case of a corrupted DLL file, in which case, you can try re-registering the system file or replace the file with a fresh copy downloaded from Winbindex short for Windows Binaries Index – make sure to place the file in the System32 or SysWOW64 folder as the case may be.
To re-register a DLL file, follow these steps:
- Open command prompt as an administrator.
- In the elevated CMD prompt, type the command below and hit Enter. Substitute the PathToModule placeholder with the full path to the DLL file.
regsvr32 twinapi.appcore.dll
