Upon installing Windows 11, users encounter numerous pre-installed applications, promotional tiles, and cloud-connected features. These apps are organized in two phases: system-level staging and user-specific activation. The AppX Deployment Service registers these apps for users, creating app data folders. Microsoft also embeds custom app shortcuts and trial software into the Start menu using LayoutModification.json. During setup, Microsoft's Consumer Experience feature connects to cloud servers, downloading app placeholders that are pinned to the Start menu. Local search is integrated with Bing by default, sending requests for suggestions and promoted content.
To clean up Windows 11, users can uninstall non-essential applications through Settings, but this only removes them from the user profile. To permanently eliminate app templates, PowerShell commands can be used. Users can disable promotional content in Settings under Personalization and Privacy & Security. To sever Bing integration from search, modifications in the registry editor are required. The Task Manager can help manage startup applications, allowing users to disable non-essential third-party apps.
While removing unnecessary components can improve performance, essential packages like Edge WebView2 runtime, Microsoft Defender, and the Microsoft Store should be retained to avoid system errors. Regular maintenance is necessary, as Windows updates may reinstall previously removed apps.
