"Run as System"-detection is failing in non-english versions of Windows

[kaivonderchrom]

Hi,

thank you for your great work it helped me a lot! Only one thing I like to add, if your scripts checking, if it´s runing in SYSTEM context, it´s done via a string-compare to the username in line 153:

if($CurrentUserName -ne 'NT AUTHORITY\SYSTEM')

This is failing in, e.g. the german version, because it´s named "NT AUTORITÄT\SYSTEM". So I changed the check and used the well-known SIDs for it:

$CurrentSID = [System.Security.Principal.WindowsIdentity]::GetCurrent().User.Value
if($CurrentSID -ne 'S-1-5-18')

(SIDs can be found here: https://docs.microsoft.com/de-de/windows/security/identity-protection/access-control/security-identifiers)

Maybe it´s helpful in the New-AovpnDeviceTunnel.ps1 and Remove-AovpnDeviceTunnel.ps1.

Thank you!

Yours

Kai
