Windows 11, as a proprietary operating system, includes telemetry, pre-installed applications (Microsoft Teams, Xbox, Copilot, etc.), and background services that many advanced users consider invasive or resource-heavy. Ghost Spectre (a handle used by an independent developer or team) produces custom ISOs that strip these components. The naming convention typically follows Microsoft’s version numbers (e.g., Windows 11 22H2 Ghost Spectre, 23H2, 24H2). The “25H2” designation refers to the expected release in the second half of 2025. The “Fixed” tag is appended to indicate patches for prior issues, such as broken Windows Update functionality, driver incompatibilities, or Defender false positives.
