Microsoft patched CVE-2025-48804 in July 2025, but researchers at Intrinsec have now demonstrated BitUnlocker, a physical-access downgrade attack that can bypass TPM-only BitLocker protection on Windows 11 systems in under five minutes. The uncomfortable lesson is not that BitLocker is suddenly...

RADX Technologies announced on May 12, 2026, a $2,499 NVIDIA T400-based PXIe graphics module intended to help PXIe test-and-measurement systems running Windows 11 avoid security compromises caused by obsolete integrated GPU drivers. The product, the PXIe-GPU-T400, is not being pitched merely as...

On May 10, 2026, CNX Software published a first-person account of a Khadas Mind 2 BIOS update that turned a five-minute Windows 11 firmware job into a two-hour BitLocker recovery detour. The story is not remarkable because BitLocker reacted to a firmware change; that is exactly what it is...

Microsoft’s April 14, 2026 Windows security updates, including KB5083769 and the later KB5083631 preview, are blocking the psmounterex.sys kernel driver used by some backup tools to mount disk images on Windows 11 systems. The newly public registry workaround is therefore real, but it is also...

Microsoft said in January 2026 that Microsoft Defender Antivirus, the security engine built into Windows 11, provides enough everyday protection for many users when default protections remain enabled, Windows Update is current, and downloads are handled deliberately. That is not a throwaway...

Microsoft’s latest guidance on Windows 11 security settles a question that has lingered for years: for most people, Microsoft Defender is enough. In a new Microsoft Windows article published in April 2026, the company says Windows 11 includes built-in antivirus protection that is active by...

Microsoft is once again making a very public case that Windows 11 does not need a separate antivirus subscription for most people. That message is not entirely new, but the company’s latest wording is notable because it comes at a moment when consumers are still being nudged by aggressive...

Microsoft’s latest Windows 11 security guidance settles a question that has lingered for years: for many users, Microsoft Defender Antivirus is enough. In a new Microsoft article, the company says Windows 11 includes built-in antivirus protection that is active by default, continuously updated...

Microsoft’s latest guidance on Windows 11 security is simple, but it lands in a noisy market: for most people, Microsoft Defender Antivirus is enough, and third-party antivirus is no longer a default necessity. That does not mean every PC owner should uninstall their security suite tomorrow, but...

Microsoft is making a familiar but still consequential argument: for most Windows 11 users, the built-in security stack is enough. That message matters because it cuts against a long-standing assumption that “real” protection requires a paid third-party antivirus suite. It also arrives at a time...

The company now says the built-in protection stack in Windows 11 is designed to run by default, update automatically, and handle the everyday...

A dangerous fake Microsoft Windows Update is being used as a malware lure, and the threat is more sophisticated than a crude phishing page or a broken installer. Instead of relying on obvious warning signs, the campaign mimics Microsoft support, borrows the language of Windows servicing, and...

A convincing fake Windows 11 24H2 update is making the rounds, and the danger is not a broken patch or a botched reboot. It is a malicious installer disguised as a Microsoft download page, built to steal passwords, browser sessions, payment data, and other sensitive information from unwary...

Choosing the right antivirus for Windows 11 is no longer just about catching classic viruses. In 2026, the real test is whether a security suite can stop ransomware, phishing, and credential theft without turning a fast PC into a sluggish one, and whether it adds meaningful layers beyond what...

Windows 11’s built-in security stack is now strong enough that many users no longer need to treat third-party antivirus as a default purchase. Microsoft’s own guidance emphasizes that Microsoft Defender Antivirus is active by default, updated continuously, and paired with layers like SmartScreen...
