Windows 10: Opening start menu causes any left click to open the contextual menu (right click) on top...

Hello!

When I'm opening the start menu after a fresh startup, my left click works properly but opens the contextual menu. However, if I open the search bar, I get completely locked out of the start menu (I can still alt+TAB out of it) because of the contextual menu on top of it. It looks like I'm constantly right clicking. This persists through computer restarts.
edit: These "constant right clicks" seems to persist even when going into the windows settings (metro-style) or when using win+TAB.


So far I've tried:

• Connecting on another account.
• Plugging in only my mouse / only my keyboard.
• sfc /scannow in Windows Powershell (admin)
• Search & Indexing Troubleshooter
• Force-closing Cortana to restart it. It had some effect: the menu didn't pop up until my next left click.

None of these fixed anything for me.

I'm unsure what to do / how to fix that. Help would be appreciated.

:)

 

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”}

 

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?

 

crashed. Now start menu opens in upper left corner and not clickable


win10 randomly crashed while idle. Some kernel security bsod.

after reboot, the start menu does not open in the lower left corner. It opens in upper left corner, and none of the menu is clickable. I have to use keyboard arrow keys to navigate.

Also, when I start typing words to search for apps, the search menu opens full screen.

My start menu is corrupted. How do I restore it? Event viewer suggested my .dat file is corrupted.

Even creating brand new user, the start menu still opens in the upper left corner (while the start button is in the lower left corner), and the menu is not clickable for the new user.
