What it changes
Receive window auto-tuning level: Normal
Before anything is written, the review screen shows this setting's current value on your PC next to the new one.
Why it helps
Disabled auto-tuning cripples download speeds on fast or distant connections; Normal fixes that.
Trade-offs
None - this is the Windows default.
Evidence
Strong evidence means: documented by microsoft or consistently measurable. Expected impact is noticeable (2 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 Network & latency 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.
