12th of June 2020

Created by: Revision

Special thanks to RavenouZ for testing and always providing amazing feedback!

    • Can be re-installed through Store if wanted


  • Language install bug

  • Windows Auto Update bug

  • BitLocker Error


  • Starting with 2004 S1.0 and up UAC will only partly be disabled in S versions, as this will render Edge (Chromium) fully functional. This may introduce other bugs, such as the DirectX 9.0 Web setup bug shown here.

    • This is easily fixed by running the the setup in elevation (administrator mode), so right click the installer and hit "Run as administrator".

    • If you do not need Edge and don't run into any elevation issues, you may want to fully re-disable UAC. We've provided you with a solution in Workspace.

  • Default System Sounds remain pre-disabled in ReviOS. Normal audio works as it's supposed to, only the Sounds are disabled.

    • If the community deems this an unnecessary change - Revision will resort back to the original System Sounds in coming builds.
