I think the problem here is that setx.exe doesn't notify the system of 
the change, so cscript.exe doesn't update the process environment.

May be cscript.exe doesn't support updating the process environment at 
all, so wpkg.js must be made aware of that change internally.

The OPs question could be solved by a DOS command script using "REG 
QUERY" to read the registry and "FOR /F" to parse the output.
