How to turn on ransomware protection in Windows 10 & 11? With 92 disclosed attacks taking place in January of this year alone, it’s clear that ransomware is one of the most significant cybersecurity threats to both organizations and individuals. To help protect users, Windows 10 & 11 offer built-in ransomware protection, providing a first line of defense against these attacks.
In this guide, we’ll discuss Microsoft’s ransomware protection and walk you through 3 simple steps on activating this feature in Windows 10 & 11. Following that, we’ll show you how to unlock proactive security with BestCrypt Data Shelter.

What Is Ransomware Protection in Windows 10 & 11?
Windows 10 & 11 include built-in ransomware protection as part of its Windows Security suite. Powered by Microsoft Defender Antivirus, this feature helps safeguard your files by preventing unauthorized applications from modifying or encrypting them. The primary tool for ransomware protection is Controlled Folder Access, which restricts access to critical folders and ensures that only trusted applications can make changes.
Is Windows 10 & 11 Ransomware Protection Enough?
Although Windows 10 & 11’s built-in ransomware protection offers essential safeguards, it has some notable limitations. Let’s take a look at 3 of them:
- Limited Customization
Windows Defender provides a default policy for ransomware protection with limited customization options. Users can protect folders in a basic manner but lack granular control over specific files or data types, potentially leaving certain assets less secure. - Passive Protection
The ransomware protection in Windows 10 & 11 operates as a passive solution; once enabled, it doesn’t offer ongoing guidance or updates based on user behavior. This static approach may not adapt to evolving threats or individual usage patterns, reducing its effectiveness over time. - Dependency on Windows Antivirus
Activating ransomware protection requires enabling Windows Defender Antivirus. Users preferring third-party antivirus solutions will find that the Controlled Folder Access functionality is disabled, meaning they will also need to find ransomware protection from elsewhere.
