Click Add, Windows 10. Name your Script. Normally I use a name which makes sense to other Administrators. In my case Notepad++ Install. Click Next. In the next Screen upload your PowerShell script you have created above and select options shown in the Image below:
Click Next, Assign it to Users or Device Azure AD group/s and Voila. Your Notepad++ Application will be deployed to the selected group. There will be no Toast notifications or Prompts on the devices. Notepad++ should appear in Start Menu.
