Between Windows PowerShell v5.1 and PowerShell v6.x I’ve noticed an Update-Help difference.
In Windows PowerShell v5.1 I can just do this:
from an elevated prompt.
In PowerShell v6.0 and V6.1 previews I have to give the UI culture I want
Update-Help -UICulture en-US –Force
All instances – PowerShell v5.1, v6.0.3 and v6.1 preview 4 are running on a single Windows 10 machine. The UI culture is en-GB for all PowerShell instances and versions.
Not a major problem now I’ve tried using the en-US culture but it explains why I wasn’t getting help before.
