Windows 10: Unknown Tiny Button on Right Side of Start Menu

A few days ago, this tiny "button" appeared in my start menu:When clicked, the button "pops"/shrinks/reacts like a radio options button, but does not change in appearance nor does it appear to do anything: it shrinks like this while it is heldI am using Windows 11. I would like to identify what this button is/does and remove it.

:)

 

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”}

 

Start menu button not working??

I found this suggestion on this website:

I followed these steps and it worked for me. Hopefully it will work for you too:

Step 1: Right-click the Start button and select Command Prompt (Admin) from the context menu.

Step 2: Type Powershell in Command Prompt and press Enter.

Step 3: Paste the following text in the Powershell window and press Enter.

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Wait for the command to run and ignore the red error prompts if they arise. The Start Menu should be operational now.
