GData Keyboard Guard

In the case that G-Data is installed, and Keyboard wont work on remote desktop connections ONTO the machine with G-Data installed:

  1. Open RegEdit as Admin and find: “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GDKeyboard Guard”

  2. Create “GDKBDisabled” as 32-bit DWORD and set it to 1

  3. Reboot the Machine

This will most likely fix the issue.
