Because the kernel creates a DOS device object directory on demand, rather than at login, it cannot check whether the user is an admin during the creation process.

Microsoft is warning organizations about the impending end of support for several Windows products from 2016. These include Windows Server 2016, Windows 10 Enterprise 2016 LTSB, and Windows IoT Enterprise LTSB 2016.
