S series vs U series

S series (recommended)

  • Stability, performance and compatibility oriented

    • Minor privacy patches, still significantly better than a normal ISO

  • Full Microsoft Store, Xbox GamePass and Console Companion support

  • Only essential AppX apps integrated

    • Missing apps can be re-downloaded through Microsoft Store

  • Roughly 1.5-3 GB lighter than a normal Windows 10 install

  • Dolby Atmos support

  • Windows Photo Viewer added

U series

  • Meant for experienced and advanced users!

  • Performance and privacy oriented

    • Various patches to block Microsoft backdoors and regain user privacy control

  • Generally more minimal

  • Mediocre compatibility compared to S builds (S series are recommended to use if you prefer compatibility)

  • AppX fully removed

  • Custom Start-Menu with additional features built-in

  • Roughly 3-6 GB lighter than a normal Windows 10 install

  • Dolby Atmos, Xbox Features, Hyper-V, Smart Card, Windows Biometric and Tablet PC aren't available
