Steam is an online game service that provides digital downloads of popular PC games. When a game is purchased through Steam it is downloaded to the purchaser's PC via the Steam program. The download speed of the game, as with any download, can be influenced by a number of outside sources. Eliminating some or all of these sources speeds up the game download time and lets the user enjoy their game more quickly.
Press the "Control," "Alt," and "Delete" buttons simultaneously. Click "Task Manager" from the menu that opens.
Navigate to the processes tab. Check the list of processes for any programs that may be downloading. Close all nonessential programs that may be downloading including torrent processes such as uTorrent or BitTorrent.
Close all Internet browser windows. Ensure that Steam is the only application open.
If your download is still slow, check to ensure that you are properly connected to your Internet source.
