+## SynthRdp
+
+SynthRdp is a Hyper-V Enhanced Session Proxy Service for Windows, which can
+redirect RDP over VMBus pipe to any RDP over TCP socket, because the Hyper-V
+Enhanced Session is actually the RDP connection over the VMBus pipe.
+
+### Features
+
+- Make Hyper-V virtual machines with Windows 8 and earlier guest OSes support
+  Hyper-V Enhanced Session mode.
+- Act as a proxy service to make Hyper-V virtual machines with non-Windows
+  guest OSes support Hyper-V Enhanced Session mode.
+
+### Usage (Quick Start)
+
+- Move SynthRdp.exe to "%SystemDrive%\Windows\System32" folder in your virtual
+  machine which needs to use SynthRdp. The platform of SynthRdp.exe needs to be
+  the same as the virtual machine guest OS.
+- Open the Command Prompt as Administrator and execute the following commands.
+  ```
+  SynthRdp Install
+  SynthRdp Config Set DisableRemoteDesktop False
+  SynthRdp Config Set EnableUserAuthentication False
+  SynthRdp Config Set DisableBlankPassword False
+  ```
+
+### Usage (Detailed)
+
+```
+Format: SynthRdp [Command] <Option1> <Option2> ...
+
+Commands:
+
+  Help - Show this content.
+
+  Install - Install SynthRdp service.
+  Uninstall - Uninstall SynthRdp service.
+  Start - Start SynthRdp service.
+  Stop - Stop SynthRdp service.
+
+  Config List - List all configurations related to SynthRdp.
+  Config Set [Key] <Value> - Set the specific configuration
+                             with the specific value, or reset
+                             the specific configuration if you
+                             don't specify the value.
+
+Configuration Keys:
+
+  DisableRemoteDesktop <True|False>
+    Set False to enable the remote desktop for this virtual
+    machine. The default setting is True. Remote Desktop is
+    necessary for the Hyper-V Enhanced Session because it is
+    actually the RDP connection over the VMBus pipe.
+  EnableUserAuthentication <True|False>
+    Set False to allow connections without Network Level
+    Authentication. The default setting is True. Set this
+    configuration option False is necessary for using the
+    Hyper-V Enhanced Session via the SynthRdp service.
+  DisableBlankPassword <True|False>
+    Set False to enable the usage of logging on this virtual
+    machine as the account with the blank password via remote
+    desktop. The default setting is True. Set this
+    configuration option False will make you use the Hyper-V
+    Enhanced Session via the SynthRdp service happier, but
+    compromise the security.
+  OverrideSystemImplementation <True|False>
+    Set True to use the Hyper-V Enhanced Session via the
+    SynthRdp service on Windows 8.1 / Server 2012 R2 or later
+    guests which have the built-in Hyper-V Enhanced Session
+    support for this virtual machine. The default setting is
+    False. You can set this configuration option True if you
+    want to use your current virtual machine as the Hyper-V
+    Enhanced Session proxy server. You need to reboot your
+    virtual machine for applying this configuration option
+    change.
+  ServerHost <Host>
+    Set the server host for the remote desktop connection you
+    want to use in the Hyper-V Enhanced Session. The default
+    setting is 127.0.0.1.
+  ServerPort <Port>
+    Set the server port for the remote desktop connection you
+    want to use in the Hyper-V Enhanced Session. The default
+    setting is 3389.
+
+Notes:
+  - All command options are case-insensitive.
+  - SynthRdp will run as a console application instead of
+    service if you don't specify another command.
+
+Examples:
+
+  SynthRdp Install
+  SynthRdp Uninstall
+  SynthRdp Start
+  SynthRdp Stop
+
+  SynthRdp Config List
+
+  SynthRdp Config Set DisableRemoteDesktop False

+  decent user experiences.
