My Favorite Fix: Gamer Shuts Off Services
The Annoyance: I'm a gamer, so performance is very important to me. Unfortunately, when applications or services start running while I'm playing something, they can kick me out of the game and cause network lag.
The Fix: I use a batch file to turn off a bunch of services all at once that would cause interruptions. I stop services like Automatic Updates because it could search for or start downloading an update while I'm in the game, and that would affect my network performance. I also turn off my antivirus utility because sometimes the antivirus update will start up while I'm in a game, and if it does, it kicks me out of the game. But I need some of these services, like Computer Browser, in order to connect to my office VPN, so I have another batch file I use to turn those services back on when it's time to get back to work.
