nKill – Restart Notes after a crash
Wer kennt das nicht. Der Notes Client ist mal wieder abgestürzt und läßt sich nun beim besten Willen nicht mehr zu einem Neustart bewegen. Schuld daran sind Prozesse, die nach einem Absturz im Speicher verbleiben und den Neustart verhindern.
Zwar gibt es bereits Tools auf dem Markt, die einem aus diesem Dilemma heraushelfen können. Aber in den meisten Fällen müssen diese Tools erst installiert und nach einem Crash erst aufgerufen werden.
Daher habe ich dieses Tool geschrieben. Für die Interessierten habe ich den Quelltext beigefügt. Das Tool lauft unter Win9.x/WinME/Win NT 3.x/Win NT 4.0/ Win 2000 und XP
