This question already has an answer here:

I restarted my PC many times, I also have restarted the Windows Explorer task but it doesn't work. I cannot right-click icons on Taskbar, I can't even click on the Start menu.
EDIT: I don't know if this helps or not, but some of Windows 10 programs are missing now, such as "Groove Music" and "Store".

  • Try Ctrl+right click and Shift+right click, then normal right click. Do they help at all? – MC10 Aug 17 '15 at 0:51
  • @MC10 It does not work. – PepsiGam3r Aug 17 '15 at 4:26
  • Is there anything else you can't right click? Maybe there was a program in your previous version of Windows that added something to the context menu and now it isn't behaving corrrectly. – MC10 Aug 17 '15 at 11:55

    What about restarting the Tile Data Model Server service mentioned here: superuser.com/questions/947789/…, does it help at all? Is this a laptop with a touchpad? – MC10 Aug 17 '15 at 22:46

This fixed it for me:

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.

Search and Cortana malfunctioning can be attributed to a corrupted search index database in most cases. To fix it, all you need to do is delete and rebuilt the Search Index. To do this, head to the Control Panel. Locate the Indexing Options utility and launch it. The utility will display a list of all the locations and applications currently being indexed. Check to see if all the drives and folders are being indexed. To add an item, press Modify and you’ll be presented with a list of all locations on the PC; tick ones you require and clock OK.

How To Rebuild Windows Search Index On Windows 10

Even if all the correct locations are being indexed, a malfunctioning Search Index can render the Search function useless. Before we delve into the method, keep in mind that the index rebuilding process may take a while and will affect system performance as well until completion. To rebuild the Index, open Indexing Options. Click on Advanced Options and press the Rebuild button in the Troubleshooting section. Click OK on the confirmation prompt and the process will start.

    These steps are not working for me. – Martin Argerami Aug 20 '15 at 19:39
  • did you get any errors and what are your exact symptoms as there are multiple issues i see in this thread...for example i have no issues with cortana, just the start & taskbar would not work on mine. this fixed both – Jarrett Neil Ridlinghafer Aug 22 '15 at 22:25
  • After a lot of searching I found that Windows cannot deal with a user's directory being a junction (unbelievable). After moving the main user and appdata directories to a local one and running the commands above now the store works, start menu works, right-click on taskbar icons works. Search still does not work, though. – Martin Argerami Aug 23 '15 at 2:32

    I can confirm that this DID fix it for me on Windows 10. When I tried right clicking on any icon in the taskbar, nothing happened. I had to use windows explorer to navigate to C:\Windows\System32, find cmd, and right click to run that as administrator. Then I typed powershell, and ran the script. Now everything works! – applejacks01 Feb 2 '16 at 3:03
