Windows 10: Any windows menu Except start is broken

Hello, All of my windows menus are brokenAny of the settings menus, display, update, etc, are scrolling up and down and clicking things randomly, with no input, even with no mouse connected and touchpad disabled. I can't update due to this, and i disabled updates until Jun 10th because updates were happening without my permission and with no warning and i could not have this while doing exams.Bringing up the projection menu makes the screen flicker and refuse any kind of input.This problem was caused by a cat jumping directly onto the laptop, from the floorIt is an asus vivibook, 20gb ram, 1

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?

 

Broken/Duplicate Item in Start Menu

Okay, I ran both commands, and the broken Netflix start menu item was still there, so I restarted my computer and it was still there. I made sure the spacing was right and they seemed to have run properly, I just forgot to take a screenshot as proof before
I closed the Command Prompt.

 

Start Menu is broken after installing Windows 10

After installing Windows 10, my Start Menu got totally broken.

Most of the programs and absent in it now. They can't be found neither by search, nor by step-by-step navigation.

Some of programs are substituted for another versions.

Simultaneously, the Start Menu folder is Ok in filesystem.

So my entire Start Menu is useless now.

To run any program, I am opening Far Manager (file manager), opening Start Menu folder in it and doing search for appropriate *.lnk file.

I.e. I am doing by hand what Windows should do with it's Start Menu feature.

*.lnk files are working fine.

Various aspects of the problem were discussed in questions:

Where are ALL locations of Start Menu folders in Windows 10?

How to fix / refresh start menu in Windows 10? How to add / remove / edit items in bulk?

Can't find applications anymore in Windows 10

So, please don't suggest primitive solutions, covered there?
