What a scan changes
A general scan does not change Windows settings. It reads services, packages, registry values, event evidence, network state, storage, drivers, and related system information. Navigation is locked during the scan so the operation stays consistent, and the scan can be cancelled.
Repair risk levels
| Level | Examples | What to expect |
|---|---|---|
| Lower impact | DNS cache clear, service start, safe cache cleanup | Usually reversible or limited in scope. |
| Higher impact | App reset, package re-registration, Gaming Services reinstall, DISM/SFC | May sign you out, alter package state, take longer, or require restart. |
| Manual only | Account, subscription, policy, remote outage, reinstalling a game | The tool explains the next action but does not perform it. |
Verification after repair
Relevant checks run again when possible. A repair is not labeled successful merely because its command exited. Results can be successful, partial, pending, or failed.
Restart behavior
The tool distinguishes required and recommended restarts. It does not restart Windows without permission. Some Store, package, service, or system-file changes cannot be fully verified until after reboot.
Undo limitations
The latest repair session is kept in Repair History. Settings captured before repair can be restored where supported. Package resets, Store installations, cache removal, Windows repairs, and changes completed by external components may be only partially reversible or irreversible.
