How to fix Start Menu, Cortana, Settings and Taskbar issues on Windows 10
Since Windows 10 were published, I have faced many different issues with the latest OS. Most of the problems, identified as malfunctions in the Taskbar and several Windows features or apps. Because of these malfunctions, the user faces any of the following issues:
- Start button is not responding.
- Cortana crashes.
- TaskBar is not working.
- Windows Store cannot open.
- Unable to launch Store Apps.
- Settings won't open.
Microsoft knows the issue, but unfortunately (at least up to the time that I write this article) I haven't found a permanent fix to resolve Start Menu, Apps & Cortana problems, so I write this tutorial that contains several fixes that I have applied until today in different situations (Windows 10 computers) that have worked.

3. Right click at Application Identity service and select Properties.
4. Press the Start button and then set the Startup type to Automatic.
5. Press OK and restart your computer.
Solution 7. Re-register Modern Apps.
I write this solution last, because it doesn't have a 100% success to all the computers that I have applied it to. In several cases the problem became worst or all store apps were broken. So, use it at your own risk.
Step 1. Enable Developer Mode.
1. Navigate to Settings > Update & security.
2. Choose For developers on the left, and then place a dot at Developer mode feature. (Answer Yes at the popup window.)
Step 2. Re-register Modern Apps.
1. At Cortana search box, type powershell.
2. Right click on Windows PowerShell on the results and select Run as administrator.
3. (Answer Yes to the UAC warning message). Inside the PowerShell window, (copy &) paste the the following command & press Enter:
- Get-AppXPackage | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
4. Wait for the command to run. (Ignore any errors with red letters.)
5. Check if your issue is fixed. *
* Note: If your Apps becomes "broken" (not working) after you have applied the above solution, then the safest way to fix the problem is to perform a repair install of your Windows 10 installation.
