Steam
What is Steam?
Steam is a digital distribution, digital rights management, multiplayer and communications platform developed by Valve Corporation. It is used to distribute games and related media online, from small independent developers to larger software houses. Steam's primary service is to allow its users to download games and other software that they have in their virtual software library to their local computers. Steam-integrated games are stored as single non-compressed archive files with the extension .gcf (an acronym for game cache file). Steam allocates space on the user's hard disk for .gcf files before downloading in order to reduce fragmentation which may occur when downloading large files and performing disk access. Game cache files help to make games more portable, stop users from accidentally overwriting important files, allow for easy modification of resources, and allows for validation of content for errors. Steam provides digital rights management (DRM) for software titles, by providing "custom executable generation" for executable files that are unique for each user, but allow that user to install the software on multiple computing devices via Steam or through software backups without limitations. As such, the user is required to have started Steam while connected to the Internet for authentication prior to playing a game, or have previously set up Steam in an "offline" mode while connected online, storing their credentials locally to play without an Internet connection. Steam includes a digital storefront called the Steam Store, through which users can purchase computer games digitally.
Overview
The most used version is 1.0.0.0, with over 98% of all installations currently using this version. Upon installation, it defines an auto-start registry entry which allows the program run on each boot for the user which installed it. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version). The software is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The main program executable is Steam.exe. The software installer includes 68 files and is usually about 1.05 MB (1,098,752 bytes).
