Windows 10: Start menu and multiple other features not working properly

About a week ago, I found out that my Start Menu wouldn't appear anymore and I wasn't able to search for anything. At first I thought it wasn't that big of a deal so I didn't bother doing much, but after a while it's gotten annoying.I've also lost the ability to open my calendar, use the Xbox game bar and opening mp4 files with Films & TV probably more features but I am unsure.Is there any way to fix this besides a factory reset? I don't find the idea of losing all my files very appealing to be honest.Note: Sorry if this is in the wrong topics, I don't know where else this can go.

Feature suggestion: Add right-click menu

Suggestion: Please add a Windows 7 Jump-List and/or right-click menu to the GPU-Z icon in the Windows taskbar. Possible menus in it would be "Exit" and "About GPU-Z...".
Maybe also "Switch to tab 1/Switch to tab 2/Switch to videocard 1/Switch to videocard 2" too.
Examples of programs that have such menus are ICQ, Skype, AIM.

NOTE: It seems for a right-click menu, Windows 7 is not needed - it works on WinXP and Vista too.
But even a Windows 7 Jump-list may be good enough.
What do you think?

 

Start menu not working

I found the following article, ran the suggested powershell command and my start menu is working again. Here it is as I found it:
Go to Start menu button and right click on it. This will open the contextual menu, after which you need to select Command Prompt (Admin). Once Command Prompt is open, go ahead with the following steps.

• Type and enter: Powershell
• Type the following: Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
