Windows PC maintenance checklist
Simple, safe PC cleanup and maintenance habits help when a Windows laptop or computer is running slow. This checklist focuses on review before removal—not aggressive “one-click fixes.”
Review storage before cleaning
Check which categories use space. Remove only files you recognise, and avoid deleting system folders manually.
Review startup apps
Too many startup programs can slow sign-in. Disable optional apps one at a time so you can reverse a choice if needed.
Protect important accounts
Use unique passwords and two-factor authentication for email, banking and software accounts.
Keep your main protection enabled
Use Windows Security or another established security product as your primary protection. GuardTune is currently a Beta with a limited antivirus and local monitoring foundation; its broader protection capabilities are still under development.
