What installation variants are available on Windows 10?

The following variants for an installation on a Windows 10 device are possible:

• Installation from the Microsoft Store
  This is the easiest option, recommended my Microsoft. The user only needs access to Microsoft Store. Installation and update processes do not require the user to take any further action.
  
  

• Installation via Microsoft Business App Store
  With this option, the IT department "procures" the app centrally and distributes it to the respective users. The IT department can control who should be able to use the app. Further information can be found in the Microsoft documentation below: https://docs.microsoft.com/en-us/microsoft-store/microsoft-store-for-business-overview 
  
  

• Installation via an MDM system
  Depending on the MDM system used, this option provides an installation which is technically comparable to the App Store variant.
  
  

• Side Loading - Direct app installation
  Only in thoughtfully pre-defined scenarios, this should be considered as an option. The app is installed without processing through Microsoft Store.
