Frequently Asked Questions

Does Microsoft Defender require a paid subscription in the UK?

Yes, to use the comprehensive cross-device Microsoft Defender app, you need an active Microsoft 365 Personal or Family subscription. The built-in Windows Security on PCs is free, but the standalone app requires the subscription.

Why won't Microsoft Defender open on my device?

This can happen if your operating system is outdated, your Microsoft account is experiencing synchronization issues, or the app itself requires an update. Check your respective app store for updates and verify your OS version.

No, the core features and device protection capabilities of Microsoft Defender remain the same across both regions, provided your subscription is active and your software is up to date.
