Summary: Find Windows capabilities with Windows PowerShell on Windows 10.

 How can I use Windows PowerShell 5.0 on Windows 10 to determine capabilities such as handwriting,
           optical character recognition (OCR), speech, and text-to-speech on my installation?

 Use the Get-WindowsCapability cmdlet, specify the -Online parameter, and filter for a state of Installed,
           for example:

Get-WindowsCapability -Online | where state -eq 'Installed'

            Note This command must be run elevated.
