In...

The latest Windows 11 April update is doing something quietly important: it now tells you whether your PC has received Microsoft’s newer Secure Boot 2023 certificates. That matters because the older certificates issued in 2011 begin expiring in June 2026, and Microsoft has been working to move...

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’s latest Windows 11 security guidance makes a long-running debate much simpler: for most people, a third-party antivirus is no longer necessary.

Microsoft’s CVE-2026-32073 is the kind of Windows security advisory that makes defenders stop and re-evaluate their patch queue: it is a local elevation-of-privilege flaw in the Windows Ancillary Function Driver for WinSock, better known as AFD.sys, and it is already being tracked as a...

A successful attack against CVE-2026-40385 is not described by Microsoft as something an attacker can just fire off at will; instead, it depends on conditions outside the attacker’s control, such as knowledge of the environment, preparation to improve reliability, or, in some cases, positioning...
