Speed
Slow PC — first pass
Slow usually means full disk, noisy startup, or background CPU. Calm first pass.
- Free space on C: (aim for 15%+).
- Startup apps: disable what you do not need (keep security tools).
- Task Manager: note idle CPU/Disk hogs.
- One antivirus quick scan — do not stack cleaners.
- Pending Windows updates, then one reboot.
When to book: Disk clicking, boot loops, or ransomware fears.
