"ADD_EXPLORER_CONTEXT_MENU_OPENPOWERSHELL" Does not work properly

Steps to reproduce

adding ADD_EXPLORER_CONTEXT_MENU_OPENPOWERSHELL=0 to msiexec options for 

Powershell 7.0.3
&
Powershell 7.1.0

does not work, as context menu options are still added regardless of the value set.

Expected behavior

Powershell installer should not add context menu option to registry if value is set to 0

Actual behavior

Powershell installer is still adding context menu for powershell in explorer window

Property condition checks in Windows Installer are traditionally, is it set or not? 0 is not treated as false. This is true of Winodws Insatller standard properties as well. If you want to force a property to “off” (undefined), set it’s value to nothing:

msiexec /i powershell.msi /l*v "%TEMP%"\install.log" /qn ADD_EXPLORER_CONTEXT_MENU_OPENPOWERSHELL=
