Did you know that Windows Vista and Windows 7 reserver 20% of your bandwidth for the system? So, if you did not disable the bandwidth limit, you should probably do so to speed up your internet during Windows updates and other Windows tasks that require bandwidth.
A common believe is that Windows takes 20% of your bandwidth and reserves it. Of course, this is not true! Disabling the bandwidth limit will not magically speed up your internet, it will simply not allow Windows-related tasks that require bandwidth (e.g. Windows Updates) to reserve bandwidth when they need it. Let’s say you’re playing a game and you enabled automatic Windows updates, you will then suddenly experience significantly more lag when this setting is enabled.
