Learn why security updates matter and how to check update status.
Software updates often include fixes for security vulnerabilities. Open Settings, select Windows Update, and check for updates. Restart when prompted so installed fixes can take effect.
Before you begin
- Save your work and close unnecessary applications.
- Use built-in settings or the software publisher’s official support resources.
- Avoid downloads from pop-ups, unsolicited messages, or unfamiliar file-sharing sites.
Recommended next steps
Keep your operating system, browser, and security tools updated. Review alerts carefully and do not disable protection just to make an unfamiliar download run.

Frequently asked questions
Should I use two antivirus products at once?
Usually, one active real-time antivirus product is the better choice. Multiple products can conflict or affect performance. A separate on-demand scanner may be used when compatible.
Where should I download security software?
Use the official publisher website or a trusted app store. Check the publisher name and avoid unfamiliar download buttons.
