Powershell getting values via regex

Question

Normally , I can catch values beginning with Windows Server like below script. But I want to get version number for operating systems as well.

Windows Embedded
Windows XP
Windows 7  
Windows 10
Windows Server® 2008 Standard
Windows Server® 2008 Enterprise

So , it will be only 7 ,XP , 10 , Embedded , 2008 inside version variable.

Script :

$server = Get-ADComputer -Filter "Name -eq '$computer'" -Properties OperatingSystem -ErrorAction SilentlyContinue
$version = ([regex]'Windows Server (\d+)').Match($server.OperatingSystem).Groups[1].Value

There is an ® symbol, try Windows Server\D+(\w+) to match it and spaces, too. \w will match letters and digits (and _, too). — Wiktor Stribiżew

You could also try Windows(?: Server)?[^\w\r\n]+(\w+) regex101.com/r/iRhmJT/1 — The fourth bird

This match every line and capture exactly what you want :

Windows(?: Server)?[^\w\r\n]+(\w+).*

That is an awesome solution! :-) Note that just to get the value in the group, you can omit .*

I was wondering if PowerShell would still match the line without the .*, thank you for this precision ! :)
