Working in XP Mode is the default 16-bit color depth, which can cause problems with some applications. It is associated with the default limit on the number of colors in a remote desktop connection (remote desktop). Increasing the number of colors is possible by turning off the integration of components, resulting in a lack of access such as a shared clipboard and transfer disks - but allows you to work in 32bit color depth. The second method is to modify the parameters of a terminal session, allowing the integration components are included and the number of colors increases to 24bit.

Changes can be made in any of the two keys:

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

or

HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Terminal Server \ WinStations \ RDP-Tcp

should be added or if there colorDepth modify the entry (dword) value of 4, which allows you to work at High (24bit).

Unfortunately at the moment it is not possible to include 32bit color depth integration of components during operation.
