Windows Security Features include more controls than many users notice, and most do not require a separate subscription. The exact options available depend on your hardware, Windows edition and whether an administrator manages the device.

Check These Built-In Protections
Open Windows Security from the Start menu. Review Virus & threat protection, Firewall & network protection, App & browser control and Device security. In supported systems, Secure Boot and the Security Processor details appear under Device security. SmartScreen and reputation-based protection can warn about potentially unsafe apps and downloads, so leave them enabled unless an approved administrator has a specific reason to configure them differently.
Enable and Verify
- Open Windows Security and check that real-time virus protection is active.
- Review firewall status for Domain, Private and Public networks; do not turn it off to fix a single app.
- Open App & browser control and review reputation-based protection settings.
- Check Device security for Secure Boot and other hardware-backed protections available on your computer.
- Restart after firmware changes and confirm that Windows still boots normally.
Advanced Features Need Compatible Hardware
BitLocker, Secure Boot and memory integrity may depend on device support and firmware configuration. Save recovery keys before making disk-encryption or boot changes. If the computer belongs to an employer, contact IT before changing security policy.
Frequently Asked Questions
Are all security options available on every PC?
No. Hardware support, Windows edition and organization policy affect which controls appear.
Should I turn off the firewall for better gaming?
Usually no. Create a narrowly scoped app rule if needed instead of disabling the firewall for an entire network.
