How to Activate Windows Defender

Windows Defender (now called Microsoft Defender) is a built-in antivirus and anti-malware program in Windows. Here's how you can activate it:

For Windows 10 and 11:

1. Open Windows Security:
   • Press Win + I to open Settings.
   • Navigate to Update & Security > Windows Security.
   • Click on Virus & Threat Protection.
2. Enable Real-time Protection:
   • In the Virus & Threat Protection window, click Manage Settings under "Virus & Threat Protection Settings."
   • Toggle Real-time protection to On.
3. Ensure Defender is the Default Antivirus:
   • If you've installed a third-party antivirus, Windows Defender may be disabled. Uninstall the third-party antivirus if you want to use Defender instead.
4. Update Windows Defender:
   • Go to Windows Security > Virus & Threat Protection > Check for Updates to ensure Defender has the latest definitions.

For Older Versions (Windows 8/7):

• Open the Control Panel and search for Windows Defender.
• Enable it if it’s not already running. Note that support for Windows 7 has ended, and using newer systems is recommended for optimal security.
