C# Kill all processes not essential to running Windows

Question

I have an application. If the application is not used in 15 mins it needs to closes all other applications (forced closed) and the timer starts again. I do not want to crash windows 7 doing this. So far I have the following:

Process me = Process.GetCurrentProcess();
foreach (Process p in Process.GetProcesses())
{
    if (p.Id != me.Id 
        && p.ProcessName != "winlogon.exe" 
        && p.ProcessName != "explorer.exe"
        && p.ProcessName != "System Idle Process"
        && p.ProcessName != "taskmgr.exe"
        && p.ProcessName != "spoolsv.exe"
        && p.ProcessName != "csrss.exe"
        && p.ProcessName != "smss.exe"
        && p.ProcessName != "svchost.exe "
        && p.ProcessName != "services.exe"
    )
    {
        p.Kill();
    }
}

Sadly windows dies (blue screen). Is there any way I could close all the processes for the active use then hopefully Windows may survive.

First, set up auto-logon on the public PC.

Then, your program just has to reboot.

Bonus points if you set up steady state or use a product like Deep Freeze, System Safe, or Time Freeze. Those products even have an option for rebooting the computer to a clean state after a period of inactivity...
