SESSIONID.EXE – Query Terminalserver Session ID


I was looking for a way to display the session-ID of my current terminal server session regardless of the protocol I’m using in a batch file. I tried numerous workarounds by parsing the output of qwinsta.exe or quser.exe – but both ways didn’t work in a reliable manner.

After some research, I figured out that the session ID is available as a property within the .NET Framework. Therefore, I decided to write a small executable that will output the session id.


Attached to this post you’ll find the SESSIONID.EXE – feel free to use it within your project.

Here are some code snippets how to use the sessionid.exe:

FOR /F "tokens=*" %%A IN ('sessionid.exe') DO SET SESSIONID=%%A

Change Clientdrive Name and Icon (Example: Mein IGEL)

Today I created a script to make it easier for IGEL Linux ThinClient users to find their client USB drives. On IGEL Linux ThinClients, all USB client devices are mapped under the virtual client drive A: (clienta$). Unfortunately, it isn’t that easy to recognize for the regular users in the Windows Explorer if they are connected to a XenApp or XenDesktop machine.
Therefore I decided to make it a lot easier for the User – and here we go – that’s how it looks now:

So what do we need to do to get there? I wrote a batch script that does the Job for you – this script needs to be run everytime a user logs on to the XenApp or XenDesktop session. This can be done with the regular login script or with group policy preferences – for my first implementation I did it with GPP and used item level targeting for specifying an Active Directory Group.

Here’s the Script:


You need to customize the Script regarding the path to the IGEL icon file to fit your environment. For Copyright reasons, I can’t offer an IGEL icon file for download – you have to create your own.

XenDesktop: Change mouse scheme to speedup user experience

On many XenDesktop installations with Windows 7 VMs I ran into a problem regarding the mouse performance. The mouse seems to be quite slow and slaggy if you’ve loaded the Win7 Aero theme.
This is caused by the mouse scheme “Windows Aero”. You need to disable this either in the default profile or via group policy preferences during login:

HKEY_CURRENT_USERControl PanelCursorsScheme Source
Scheme Source=dword:00000000

I assume that the same setting is gonna work on Windows 8 based VDI machines, but I don’t have tested this so far.
