If you are a Windows 10 user, you are probably aware that Microsoft sends continuous updates to ensure system stability, protect against security threats, and enhance user experience. Updates come either to add new features, known as “major updates,” or to fix bugs and security vulnerabilities, known as cumulative updates. In this article, we will focus on the importance of Definition Updates and their role in keeping Windows 10 secure.
Comparatively, Definition Updates are smaller and faster than Cumulative Updates and Feature Updates in Windows 10. Users may not even notice these updates being downloaded and installed unless they actively check the Windows Update settings. These updates are essential for keeping Windows Security up to date and protected against the latest security threats.
Windows Security, formerly known as Windows Defender, is Windows 10’s built-in antivirus program. It automatically runs in the background to protect your computer from malware and viruses. Definition Updates play a crucial role in updating Windows Security’s database with the latest detected threats.
These updates help Windows Security detect and protect against new threats as soon as they are discovered, ensuring your system remains secure. While every antivirus program receives such updates, Windows Security integrates them seamlessly through Windows Update.
You can manually check for Definition Updates by accessing Windows Security and navigating to the “Virus & threat protection” section. Click on “Check for updates” to ensure your system has the latest protection.
It’s important to distinguish between Definition Updates and other security updates. While security updates address existing vulnerabilities, Definition Updates preemptively update the database to keep your system protected against emerging threats.
While Definition Updates are small in size, it’s not recommended to disable them. Disabling Windows Update altogether is the only way to stop receiving these updates, but it will also prevent other essential Windows 10 updates. Additionally, if you install a different antivirus program alongside Windows Security, the latter will disable itself, resulting in a loss of Definition Update support.
