Microsoft no longer claims that Windows 11 has all the protection that you need

Back in April, Microsoft published a detailed blog post explaining how Windows 11 contains a bunch of built-in protections that actively protect your data. The blog was titled "Best antivirus software for 2026: The built-in Windows protection you need", and emphasized the idea that the operating system natively integrates security features, implying that you don't really need anything else because you already have Windows Security. Now, the company has inexplicably removed this blog post.

The removal of this blog post, previously available here, was first spotted by AV-Comparatives and highlighted to us by Neowin forum supervisor goretsky, who noted that the blog post was a bit controversial in the first place due to its strict stance regarding third-party antivirus solutions.

The blog was originally published on April 9 on the Microsoft Learning Center, and looking at archive.org snapshots, we know that it was available until at least May 11. However, a snapshot from May 24 indicates that it was removed without any public announcement, and now redirects to the Learning Center homepage.

In the contents, Microsoft had explained the benefits of Microsoft Defender Antivirus, Microsoft Defender SmartScreen, Smart App Control, native ransomware mitigation processes, and more. One of its more controversial aspects was Microsoft's emphasis that you don't really need third-party security solutions. One section in particular highlighted that:

Do you still need third‑party antivirus in 2026?

For many Windows 11 users, Microsoft Defender Antivirus covers everyday risk without requiring additional software. The choice to add third‑party antivirus depends on how you use your PC and which features you value.

When built‑in protection is enough:

Windows antivirus protection is usually sufficient when Windows 11 runs with default protections enabled, updates are installed regularly, and software downloads are deliberate. Microsoft Defender Antivirus and SmartScreen already address common threats such as malicious files, phishing sites, and unsafe installers.

When additional tools may help:

You might consider extra security software if you manage multiple devices, share devices with family members, or want services like identity monitoring or parental controls.

Each added tool increases background activity and complexity, so choose tools that match real needs.

Of course, many Windows 11 customers (including yours truly) do only rely on Windows 11's native protection mechanisms and don't feel the need for alternatives, Microsoft's public stance on the matter may have rubbed some partner vendors the wrong way, leading to its subsequent removal.

We checked similar keywords online and could not locate recent articles from Microsoft still holding this stance, which indicates that the removal is intentional. That said, we have still reached out to Microsoft to understand the company's reasoning behind this move.
