Check Install Skype version on Server PowerShell

If you want to check with Date wise when version was install on server run this command.

Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | ?{$_.DisplayName -like "Skype for Business*"} | sort DisplayName | ft -AutoSize DisplayName, DisplayVersion, InstallDate

If you only need to know the install version .

Get-WmiObject -query ‘select * from win32_product’ | where {$_.name -like "Skype for Business*"} | sort Name | ft -AutoSize Name, Version

Thanks.
