Service WdiSystemHost: Manual

Before anything is written, the review screen shows this setting's current value on your PC next to the new one.

Why it helps

The service no longer starts at boot unless something needs it.

Trade-offs

Troubleshooters and automatic problem detection run only when started.

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?

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.

Apply it safely with Nexus

Preview the exact change, apply it with its original value recorded, and undo it in one click if you change your mind.
