Windows only: Free application Disable Startup keeps just any old app from adding itself to your list of startup applications, keeping your boot time snappy and RAM happy. At its core, Disable Startup is a startup manager similar to the built-in Windows System Configuration Utility. It does the trick if you just want to use it for that, but it's really nothing special strictly as a startup manager. If you're willing to run Disable Startup in your system tray (which will cost you about 4MB), it'll closely monitor your startup applications for new additions. The app gives you the option to disable all new startup entries, warn you when new startup apps are added, or allow any new additions. Likewise, Disable Startup can prevent new software installations from changing your IE start page. It may not be worth the added system tray app for some, but if you install a lot of software that ends up sneaking entry after entry into your list of startup apps, this simple utility is perfect. Disable Startup is a free download, Windows only.
