Keeping your HP laptop safe on Windows 10 is crucial to protect your data and privacy. Start by enabling Windows Defender, the built-in antivirus and malware protection, and ensure it is regularly updated. Keep your operating system and all software up to date to patch any vulnerabilities. Create a strong and unique password for your user account, and consider enabling multi-factor authentication for an extra layer of security. Be cautious when downloading and installing software, and only obtain them from trusted sources.
