The GDFTrace tool will decode and verify all ratings information present. Use the August version or later of these tools. The GDF for a game provider typically contains no rating information, and it is subject to the settings for unrated content.
Newer ratings data are ignored on versions of operating systems without support for them. For more information about making a game compatible with standard user privileges, see the DirectX article User Account Control for Game Developers.
If DirectInput peripherals are also supported, then DirectInput can also be used. All references to common controller triggers and buttons must use the Xbox names. At a minimum, an option to return to game menus must be available. This requirement gives gamers freedom of choice to use either the Xbox controller or the keyboard and mouse, depending on which input method is more natural and intuitive interface.
We recommend that menu navigation be implemented to use the widely accepted standard controller buttons:. For more info, see XInput. It is recommended that DirectInput not be used to implement keyboard or mouse controls. With the Windows 3D desktop, a particular aspect ratio or resolution cannot be assumed, because of the following factors:.
Ideally, the game defaults to the native aspect ratio of the display. However, obtaining this information reliably can be a challenge, so as a more general solution the game can assume that the desktop is running at the native aspect ratio. If the game uses Direct3D, then the minimum version supported must be Direct3D 9, and Direct3D must be the default renderer selected. Direct3D 8 and earlier versions are supported by remapping legacy interfaces. Use of versions of Direct3D newer than Direct3D 9 is strongly encouraged.
See the Games for Windows Showcase S. Requiring Direct3D 10 or Direct3D 11 is fully compliant with requirement 1. This typically requires the game executable to declare being DPI-aware. High-quality LCD monitors are commonplace as computer displays, and they look best when driven at their native resolutions typically , , and so on. Customers who have difficulty reading text and seeing images at this resolution often set their computer desktops to a lower resolution and suffer visual artifacts from LCD scaling.
Instead, customers can leave the resolution at the native size and change the DPI of the Windows display, thus making item and text appearance larger without sacrificing image quality. More than half of all computer displays today are set to a lower resolution than the monitor's native resolution, based on customer feedback.
Windows 7 makes this feature much more visible to customers during initial setup and when changing display settings, encouraging them to use DPI scaling rather than change the desktop resolution. Adding to the manifest is preferred, to ensure there are no race conditions with software elements such as DLLs that might initialize before the main entry point is called.
Adding the manifest element is easy to do with Visual Studio and ; create a file named dpiaware. Then, inside Visual Studio, add dpiware.
Ensure that Embed Manifest is set to Yes in the project's properties. Note that older versions of the Manifest Tool Mt. To resolve this, update Mt. Visual Studio includes a setting in the project properties, named Enable DPI Awareness , that eliminates the need for a file like dpiaware.
While full-screen applications change the display resolution, they often use window messages and metrics when setting up buffers and display rectangles.
DPI virtualization causes these full-screen display modes to appear cropped, and declaring DPI-aware will prevent these problems. The following requirements improve the overall security of games and help ensure that they work with Windows on different architectures, under different configurations, and in different modes. Every executable file that is, every file that has a. Per requirement 1.
These directories are hidden by default for individual users and for all users. If only a few features in an application require administrative privileges for example, an application that needs to configure a firewall , the main process of the application must still be run by using standard user privileges. Features that require administrative privileges must be moved into a separate process, such as an installer or configuration utility. If administrative privileges are not required, the embedded manifest XML should include the following:.
If administrative privileges are required, the embedded manifest XML should include the following:. With Visual Studio this is easily embedded by just adding a manifest. For Visual Studio and , UAC properties can be set directly in the project properties for the linker on the Manifest File page. To maintain compatibility with bit editions of Windows, games should meet the following requirements.
Many Windows Vista and Windows 7 users will run bit editions of the operating system over the life of the product, so it is crucial for applications to be compatible with this operating system. Windows on Windows 64 WOW64 allows bit code to run on bit editions of Windows, so it is not necessary that the application be native bit code on bit editions of Windows. Sixteen-bit code does not run on bit editions of Windows. Maintaining compatibility with Windows XP Professional x64 Edition is not required, but it is strongly encouraged.
For details, see bit programming for Game Developers. All executable code files typically, files with the extension. Signing a file helps users decide whether to trust an application, and assures users that files have not been tampered with. It also allows applications to run properly in locked-down environments. For details, see Authenticode Signing for Game Developers. We do not recommend signing cabinet. Any kernel-mode driver that is installed by the game must be signed with a publicly valid Authenticode certificate.
Poorly written or malware drivers can severely affect the stability and security of a system. On bit editions of Windows Vista and Windows 7, unsigned drivers do not load. This policy can also be enabled for bit editions of Windows Vista and Windows 7. Both bit and bit native versions of all kernel-mode drivers are needed per requirement 2. More information about Microsoft driver signing programs can be found at the Windows Hardware Developer portal.
Games must not fail to run on future operating systems as indicated by changes in the Windows version number, unless the End User License Agreement prohibits use on future operating systems. If the game is supposed to fail, it must do so gracefully by displaying an appropriate message to the user. Registry keys must not be read to determine the version.
Explicit version checks for the DirectX runtime must not be present in the game. These version checks must not be present in the installation that launches the DirectX runtime setup DirectSetup. When Windows users upgrade their operating systems, they should not be blocked from playing current games simply because the Windows version number has increased. Poorly written version checkers continue to create problems for software that, otherwise, works fine on newer versions of Windows or simply with the addition of a Windows service pack.
Fragile version check comparison logic for the DirectX runtime has created numerous failed installations when it is run on different versions of Windows. The DirectX version number applies only to the core operating system components. It is quite common to see installers check for a minimum OS version. This check, however, needs to be done with care to ensure that it tests for greater than or equal to, rather than simple equality, thereby locking to a specific version of the operating system.
Using Application Verifier's HighVersionLie test is a quick and easy way to determine how your installer will react to a significant change in the OS version number. Proper use of the DirectX runtime redistribution package DirectX Setup involves always launching it during installation, preferably in silent mode.
This allows the code that is provided by Microsoft to perform any required version updates. It is recommended that games that support Windows XP check for a service pack level of 2 or higher, because Service Pack 2 SP2 and Service Pack 3 SP3 provide significant security improvements, a simplified DirectX Runtime Redistribution requirement, and extremely broad deployment.
Games that rely on 3D graphics are not required to work over a remote desktop connection, but the user must be alerted when the game fails. Windows users should be able to run concurrent sessions without conflict or disruption. This is a common scenario for a Windows computer that is shared by a family, roommates, or others. A nonzero value indicates that the session is remote. For more information, see Fast User Switching. Note that Fast User Switching occurs if Parental Controls time restrictions are enabled when the user's time is up.
See requirement 1. If a game supports saving files, it must be able to save files that have long names and paths. Players are accustomed to using long names on deep paths that are supported by the underlying operating system. Long names are defined as those that contain the maximum values that are defined in the Windows SDK.
Customers can be confident that applications will install on Windows without degrading the operating system or other applications if applications use official system component distribution methods. A streamlined installation experience provides a more accessible and trouble-free out-of-box experience for games.
Installation and removal can require administrative rights. Patching can require prompting for administrative credentials, depending on frequency of update. Normal play of the game must not require administrative rights, per requirement 2. Easy installation is a Windows-centric game development philosophy that is designed to simplify and streamline the sometimes tedious and confusing process of installing games on computers that are running Windows operating systems. Easy installation is enabled by utilizing a set of technologies and best practices that reduce the unnecessary complexity and perceived risk of installing games on Windows computers.
Some traditional installations have prompts that allow non-functional installations, even though the application appears to be successfully installed. For example, a game can require a user to accept a EULA. This scenario can result in a game that fails to run because of missing components. For more information about game installation, non-traditional game installation techniques, UAC-compatible patching solutions, and handling frequent patching, see the following DirectX articles:.
Removing user-specific generated data files should be performed only for the current user and for common shared user locations. There is no robust way to scan the system to remove user-specific files for other users, even if the removal requires administrative credentials.
The game installer must not assume that it is running in the same context as the user. User-specific locations will be different from the installer and the player even for single-user systems due to administrator credentials elevation.
Therefore, when a game runs for the first time, it must perform user-specific tasks, separately from the installation process. The Windows Firewall exception dialog box must not appear when a user hosts or joins a multiplayer game. Any required configuration must be done at installation time. The setup instructions should inform the user that this operation will occur as part of the setup.
The game installer must provide an embedded manifest that designates the required execution level, per requirement 2. If the game is launched by the installer after installation is complete, it must be launched in the context of the original user.
One of the largest changes to the Windows operating system in Windows Vista is the addition of User Account Control UAC , which runs applications with reduced privileges by default. As a result, installers need to manage privilege levels accordingly.
Windows 7 also makes extensive use of UAC. While Windows 7 improves the user experience of UAC, installers must still meet the same requirements as on Windows Vista to function properly, without relying on potentially confusing virtualization behavior. Microsoft is planning on making several changes to Windows XP, including improvements to the Windows networking system, the file manager, Windows Task Manager, and other system tools. They have also developed a number of new features, which include new Live Tile features and a new start menu.
These new features will be included in the Windows XP Service Pack 1, which is not supposed to replace the older Windows Vista operating system. Microsoft has claimed that over five million people will be taking advantage of the new features when it becomes available.
As with any other software upgrade, users are encouraged to install Service Pack 1 on their computers as soon as possible. If you are like many people, your computer may not even be ready for this large Windows XP service pack upgrade, so you may want to wait until the system is completely installed and running before upgrading.
It should be noted that installing Service Pack 1 will not increase your computer's speed or functionality. However, after a few days you will likely notice a difference in the speed and operation of your computer. If you do decide to go ahead and apply the service pack, then be sure to back up your data beforehand, just in case you need to roll back your changes if something goes wrong. We don't have any change log information yet for version 1. Sometimes publishers take a little while to make this information available, so please check back in a few days to see if it has been updated.
