Answer 1

You get System because your service runs under the System account.

There is an article on codeproject that discusses the same thing .. check it out http://www.codeproject.com/KB/vb/Windows_Service.aspx

System.Diagnostics.Process[] objArrProcess = System.Diagnostics.Process.GetProcessesByName("explorer");
string strCurrentUserName = objArrProcess[0].StartInfo.EnvironmentVariables["username"];

This works for me.

Check this link which talks about getting current loggedin user from window service -

Taken from above link itself -

There can be 0 or more current logged in users. If you want all of the 0 or 1 users who are currently logged in at the console then P/Invoke to WTSGetActiveConsoleSessionId and WTSQuerySessionInformation. If you want all of the users then you'll need to call WTSQuerySessionInformation in a loop.
