Windows 10 - How to Run & Launch UWP Apps from CMD

Well, here's the general template:
explorer shell:appsFolder\[PackageFamilyName]![APP_ID]
or
start shell:appsFolder\[PackageFamilyName]![APP_ID]How to find PackageFamilyName
All UWP app folders are listed here: %LocalAppData%\Packages
The [PackageFamilyName] is the folder name of the app you wish to launch, which includes the PublisherID. As an example, Microsoft's PublisherID is 8wekyb3d8bbwe.
How to find App_ID
UWP apps are usually installed in C:\Program Files\WindowsApps. Look for the folder of the app you wish to launch and open it. Inside it, look for the AppxManifest.xml file. Open this file in Notepad or a similar text editor. Search for the string "Application ID=".
A 2nd way of finding the required strings:
The apps' XML files are all concentrated here: %ProgramData%\Microsoft\Windows\AppRepository. Open the desired XML file and search for the string "Application ID=".
Note that there may be more than one XML file associated with each app. Try opening the most recent one, and look for the XML file that's larger than 1KB.
A 3rd way of finding the required strings (via registry):
Open the registry and navigate to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AppModel\StateRepository\Cache\ApplicationUser\Data\
Inside you'll see many folders with hex numbers, each one corresponds to a certain UWP app.
In each folder, there's a value named "ApplicationUserModelId". The data of this value is what you need.
Copy the data to the command line, and simply prefix it with explorer shell:appsFolder\ .
Hit Enter, and the app should launch.

NOTE1: Some apps have more than one protocol. For example, the Mail app can be called by using explorer mailto: . The purpose of app protocols is to facilitate the use of arguments, so with this Mail app protocol, you can add a specific email to directly open a new mail to that person, for example explorer mailto:someone@home.com .
NOTE2: You can use the command "start" instead of "explorer" .

By the way, there's a entire list of shell commands that can be used in Windows 10.
All shell commands are listed under this key in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\FolderDescriptions
In each subfolder/key, there's a value named "Name" and its data is the shell command.
