How to solve the win10 system start menu and notification center can not open

problem description I used the now immature Win10 operating system, yesterday I first encountered the opening of the calculator flashing, then I found a google Click on the Start menu, type "Powershell" right click on Powershell in the search results, select “run as administrator" in the window that opens, enter the following content Get-AppXPackage -AllUsers |  Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\\AppXManifest.xml"}After waiting for a while, it is finished, suddenly found that the start menu and the notification center can not be opened (no reaction at all)~ ~ Even the calculator program gave me the solution. The above description of the problem has already been said. I can't even open the start menu and the notification center, so I can't enter the settings first. I restarted the computer and then Ctrl + Shift. + Esc pops up the task manager and clicks on the file-->runs the new task

Enter "powershell" in the open box and check the "run as administrator" Ok!

Enter the above content again in the open window

Get-AppXPackage -AllUsers |  Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\\AppXManifest.xml"} After the run is complete, try again and open it

Find the path of "Powershell" on the disk, and then open the Powershell window by right-clicking the administrator. I am using the win10 enterprise version. Maybe different versions have different solutions, if you After the installation is complete, you cannot open the start menu. You can try this method
