What it changes
Service SSDPSRV: Disabled Service upnphost: Disabled
Before anything is written, the review screen shows this setting's current value on your PC next to the new one.
Why it helps
One fewer background service running or starting on demand.
Trade-offs
Media servers, some printers and casting may not be discovered.
Evidence
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?
No. Tweaks that change a Windows service are never applied in bulk. Each one is a deliberate, individual choice.
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.
