That's cos I don't do powershell. :)
That said I copied and pasted and the result was:
ProductA v1.2.3
ProductC v1.3.5
ProductB v1.10.0
ProductD v2.0.0
The [version] thing, according to the AI, apparently tells it to sort as a
version string. The regex is there to remove the prefix because the string has
to be pure version.

That may work until someone does a really minor release and you get 5.10.1.
Humans like to break things. :)
If you treat it as a version it should just work[tm].
