Evidence

Moderate evidenceExpected impact:Small

Moderate evidence means: helps in specific situations. Expected impact is small (1 of 3): how much it can matter when this is actually the bottleneck on your PC, not a promised gain.

Is it in a pack?

Yes. It's in the Debloat pack, so that pack and Optimize everything include it. You can still untick it in the review screen.

How to undo

Switch the tweak off in Nexus, or open Restore Center and restore this change (or choose Undo last change). Nexus writes back the original value it recorded before applying, not a generic default, then reads it back to confirm.

Where it applies

Windows 11 22H2 (build 22621) or later.

Anywhere else, Nexus shows it as not applicable instead of pretending it works.
