System.Security.Principal.WindowsIdentity.GetCurrent().Name

I am getting the name as "SYSTEM" and not the logged in user's name. And I know that this is because the service is run at the system level.

I can now get the currently logged in user name. But, this requires the user to enter his user name and password when the service is being installed and I do not want that to happen.

It would be a breach in security if you could impersonate that user without them entering a password for their account.

All I'm using is a simple Sqlite database and I'm using simple queries where I have to use the windows logged-in user name.

The simplest way would be to create a small application that writes the username to a file, and to drop it in the Startup-folder.

List<int[,]> largeData; //a 5000x500 matrix
List<int[]> referenceList; //each int[] has about 10 elements
int answer;

//loops
Parallel.Foreach<int[]>(referenceList, refArray=>
{
   foreach(int[,] largeMatrix in largeData)
   {
      lock(largeMatrix)
      {
         answer = 0;

         foreach(int ref in refArray)
         {
            answer += largeMatrix[ref];         
         }
         
         //use "answer" for more processing here
      }
   }
