First of all, Cortana has to be enabled, and she can only hear if your computer has a microphone available. If she’s not enabled you might also need to turn it on. To verify this follow the step below:

On the Taskbar, in the Search window, left click. Then click on the setting button (in System Settings). Verify that the following options are enabled:

Let Cortana respond to “Hey Cortana” to talk to Cortana. Respond when anyone says “Hey Cortana” to let anyone talk to Cortana.

Make sure Cortana can hear you. Work through the wizard to set up the microphone. If there are problems, let Windows resolve them.



Try to reinstall Cortana:

Many problems related to the Cortana operation can be fixed by reinstalling it, then I write a PowerShell command to perform the process

Windows Key+X > Click Powershell (Admin) > Copy the below and paste into Powershell > Enter

Microsoft.Windows.ShellExperienceHost | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}



After that, reboot your computer.

Try to update your audio or graphics video.

Press Windows key +i then in the search box type Device Manager>Sound, video and game controllers then right-click (or tap and hold) it, and select Update Driver

Select Search automatically for updated driver software. If nothing change you can search the device manufacturer’s website driver download and install it.

If you still can’t fix your problem with the Start menu or Cortana, try creating a new local administrator account, maybe the windows profile is corrupted then move your personal data and files to the new account.
