由于与随意下载的恶意软件相关的安全问题，USB 存储设备上的自动播放功能默认不再被调用；现在，用户必须在相关设备上手动调用应用程序以安装新程序。 | 由于与随意下载的恶意软件相关的安全问题，USB 存储设备上的自动播放功能默认不再被调用；现在，用户必须在相关设备上手动调用应用程序以安装新程序。 | ||

Windows 7 includes Direct3D 11, which adds support for Shader Model 5. This brings with it the addition of GPU compute shader capabilities, the ability to run multiple shader routines at once (subroutines), dynamic shader linking (optimizing shaders during runtime) and improved performance with added multithreading support. Textures of up to 16,384 × 16,384 pixels are now supported by Direct3D 11, and meshes can now dynamically increase their level of detail through the use of tessellation, offering smoother surfaces on models with lower polygon counts. Feature levels are now supported by Direct3D 11, allowing the use of older API versions (such as Direct3D 9) while creating a D3D11 device through the WARP API. Graphics resources can now allocate more than 4 GB of video memory, eliminating the 32-bit memory limit present in older Direct3D versions. | Windows 7 includes Direct3D 11, which adds support for Shader Model 5.
