I'm new to the forums. Like many, I've had problems in the past about Window 7's notorious wireless lag-spike issue. However, after having done some tweaking today, I think I actually managed to fix the problem without downloading any network drivers/graphic drivers. I disabled SuperFetch in Services. Now, I have no spikes. I'm writing this because I'm only have an average knowledge of computer tech. and I was wondering if an advanced technician can reassure that this method can fix lag at no expense to my PC. I completely understand that my performance will drop slightly, but other than that, I've yet to encounter lag-spikes since disabling SuperFetch. I hope this help others.
