Windows 11 has faced criticism for its telemetry features, mandatory Microsoft Edge inclusion, and resource-consuming background processes that can hinder performance. AtlasOS offers a structured setup process requiring a clean installation of Windows 11 with a local account. Users download the AME Wizard and Atlas Playbook from the AtlasOS website to apply modifications, including disabling Windows Security features and replacing Microsoft Edge with alternative browsers like Brave or Firefox.
After installation, AtlasOS modifies the desktop experience, aligning the taskbar to the left and introducing a new wallpaper. It disables animations for faster application opening times and optimizes power plans for performance. Bing search is removed from the search bar, enhancing search efficiency. Privacy is prioritized by disabling telemetry services and location permissions.
Performance tests show that AtlasOS stabilizes CPU usage and slightly reduces memory consumption compared to standard Windows. Benchmark results indicate minor performance improvements, with AtlasOS scoring slightly higher in Geekbench 6 but comparable in Cinebench 2024. Users should manage expectations regarding performance gains, as the primary advantage lies in an improved user experience rather than significant speed increases.
