Why it helps
They no longer start at boot unless something uses them.
Trade-offs
Xbox app games still start them automatically; nothing is disabled.
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.
