This is an often asked question but the solution is simple:

So how does it work?
First we obtain the user’s primary access token with the WtsQueryUserToken  API call. To call this function successfully, the calling application must be running within the context of the LocalSystem account and have the SE_TCB_NAME privilege (LocalSystem has this privilege by default). Since the function returns a primary acces token we can just pass this to CreateProcessAsUser and voila!

A little while ago I wrote a little commandline tool that starts an RDP connection (with mstsc.exe) because mstsc doesn’t allow you to use the login credentials (username, password) as commandline arguments.

Arguments are:

1. Servername (string)
2. Port (integer, usually 3389)
3. Username (string)
4. Domain (string)
5. Password (string)
6. Console (integer, specify 0 for false and 1 for true)
7. RedirectDrives (integer, specify 0 for false and 1 for true)
8. RedirectPrinters (integer, specify 0 for false and 1 for true)

A friend bought a new Toshiba Satellite L40 laptop which came with Windows Vista preinstalled. The wireless connection (via the built in Atheros AR5007EG card) was very unstable and sometimes unable to connect to the access point. When connected internet speed was very slow, sometimes unable to open pages at all. First we tried replacing the preinstalled Toshiba drivers with the latest from the Toshiba site and later on the most recent from Atheros (which can be found here).  Both drivers didn’t improve the speed.  
Solution:
