When Windows 10 is acting as a host for Remote Desktop, redirected printers may stop working or cause the RDP client to crash (NT.DLL.)

This can happen when the “Easy Print” driver is installed by the host machine despite there being a proper printer driver installed. This unnecessary substitution can be turned off:

HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services

Add DWORD key UseUniversalPrinterDriverFirst and set value to 4

(Values are Enabled = 3, Disabled = 4)

In some cases, the host has to be rebooted for this to take effect.
