Cortana not showing and search is not working properly in Windows 10.

Hi Nishant,

We appreciate you for being part of Windows 10.

Before proceeding, we need to know the region where do you live.

Cortana is available in the following countries/regions: China, France, Germany, Italy, Spain, United Kingdom, and United States. Cortana is available in these languages: Chinese (Simplified), English (U.K.), English (U.S.), French, Italian, German, and Spanish 

To use Cortana, all these settings must be set to the same language:

1) Languages (this is your device language)

2) Speech language (language pack must be installed)

3) Country or region

Note: If you change your region, you might not be able to shop at Store, or use things you've purchased, like memberships and subscriptions, games, movies, TV, and music.

If any of these functions like Start Menu, Settings, Search, Cortana, Microsoft Edge, Action Center and other Windows components are not responding, follow these below methods and check if it helps: 

Method 1:

1. Open the Task manager.  Here’s a tip:  Press CTRL+Shift+ESC.

2. Click File > Run New Task

3. Make sure you have a check mark beside “Create this task with administrative privileges”

4. Type Powershell

5. Type the following in the Powershell prompt:
   $manifest = (Get-AppxPackage Microsoft.WindowsStore).InstallLocation + '\AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest

6. Close the Powershell window

7. Reboot the computer and check if it helps.

If the issue still persist, follow the below method.

Method 2:

1. Press Windows + X keys on the keyboard, select Command prompt (admin).

2. Enter the below commands one by one and hit Enter key. These commands will check and repair if there are any corrupted files 

          Dism /online /cleanup-image /restorehealth

          Sfc /scannow

3. As above, if this reports problems that cannot be fixed, stop here. There may be a memory or hard drive issue.

4. Now enter the below command in Command prompt (admin) prompt. 

          PowerShell -ExecutionPolicy Unrestricted

5. It will open the PowerShell window.

6. Now enter the below command and hit Enter key.

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

I hope the above information helps. Kindly let us know if you need any further assistance with Windows. We are glad to assist you.

Thank you.
