Launch windows app from PApps

I would find it very useful to be able to launch standard windows apps - notepad, calculator etc - directly from the portable apps platform.

I have tried puting a batch file in a named folder inside my portable apps directory, but it doesnt seem to get detected in the platform.

C:\Portable Apps\PortableApps\windows-memtest has this batch file, named memtest.bat
%windir%\system32\MdSched.exe

If I click on it it works so that isnt the problem

I've read this:
https://portableapps.com/node/21757
but its not working on that app. (unless there are a lot of changes I'd need to make to the AppInfo.ini file)

Is there an example of that working that I could follow?

Even better would be to add them as icons to the platform menu.
