Add .CPL back to $env:PathExt

[brwilkinson]

Is it possible to add in the .CPL pathext ?

I use this frequently for launching control panel items.

e.g.
appwiz
sysdm

Windows PowerShell

$PSVersionTable

Name                           Value
----                           -----
PSVersion                      5.1.18908.1000

ls env:pathext

Name                           Value
----                           -----
PATHEXT                        .COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC;.CPL

Actual behavior

 $PSVersionTable

Name                           Value
----                           -----
PSVersion                      7.0.0-preview.1

ls env:pathext

Name                           Value
----                           -----
PATHEXT                        .COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC

The ENV:Pathext was already removed on linux, so I hope Windows should still have .CPL.

• Do not add PATHEXT environment variable on Unix (Do not add PATHEXT environment variable on Unix #7697)

You could directly add new value to PATHEXT environment variable. Why must pwsh do this internally?

[brwilkinson]

This currently gets added in Windows Powershell, without it, it's a breaking change. It would be ideal to have parity with the current Windows Powershell on this.

I don't know history why it was removed.

This was inadvertently removed as part of #4942. Since this is a break from WinPS, we should put it back.
