Just so everyone is aware, ReviOS disables the Spectre and Meltdown mitigations, virtualized based security, Windows Defender, turns off and hides the ability to use Windows Update (no future security updates), disables Bitlocker, etc. Many of the performance improvements come from disabling security mitigations/processes. Just something to be aware of. I think all of these settings can be re-enabled through their Revision Tool https://github.com/meetrevision/revision-tool.
