Windows Cleanup Baseline

Use this baseline before deeper diagnostics.

1. Remove obvious startup bloat and unused applications.
2. Check storage pressure and clear temporary files safely.
3. Run update checks and confirm reboot status.
4. Validate Defender status and quick scan results.
5. Review browser extension sprawl and suspicious add-ons.
6. Measure boot time and idle memory before/after cleanup.
7. Create a short user checklist for ongoing hygiene.
