Microsoft’s Secure Boot certificates expire in June 2026, but older PCs may never get the fix

Every Secure Boot-enabled Windows PC relies on cryptographic certificates issued by Microsoft in 2011, embedded in the motherboard's firmware, to ensure a secure boot process. The first of these certificates will expire on June 24, 2026, which will affect the ability to receive future security updates for critical components of the Windows startup process. Microsoft is rolling out replacement certificates through Windows Update, marking a significant security maintenance effort. Secure Boot operates as a chain of trust with certificates stored in the motherboard's UEFI firmware, validating software before the operating system loads. The Platform Key (PK) is at the top of this chain, followed by the Key Exchange Key (KEK) and the Signature Database (DB). The replacement certificates introduced in 2023 restructure certificate management, separating responsibilities among different certificate authorities to enhance the trust model. Not all PCs are affected by the upcoming expiration; newer devices manufactured since 2024 already have the new certificates. Windows 10 users face challenges as support for this version ends in October 2025, and they will not receive the new certificates unless enrolled in Extended Security Updates. Home users should ensure their PCs are set to receive updates automatically, while enterprise environments require coordination for firmware updates before the Windows certificate update.

Microsoft’s Secure Boot certificates expire in June 2026, but older PCs may never get the fix

Every Secure Boot-enabled Windows PC relies on cryptographic certificates issued by Microsoft in 2011 for boot process integrity. The first of these certificates will expire on June 24, 2026, impacting the ability to receive future security updates. Microsoft is rolling out replacement certificates through Windows Update, requiring collaboration between Microsoft, PC manufacturers, and users. Three critical certificates will expire: the Microsoft Corporation KEK CA 2011 and Microsoft UEFI CA 2011 in June 2026, and the Microsoft Windows Production PCA 2011 in October 2026. The new certificates introduced in 2023 have a restructured functionality to enhance security. Not all PCs are affected; newer devices manufactured since 2024 come with the new certificates. Windows 10 users face challenges as support ends in October 2025, and unsupported devices will not receive updates. Home users should ensure automatic Windows updates and check for firmware updates, while enterprise environments must verify firmware updates before applying certificate updates. The first certificate expiration is on June 27, 2026.

Windows 11 is making big changes to printing, because printers are awful

Microsoft is transitioning to a universal printer driver system to address issues related to legacy printer drivers in Windows. Starting with Windows 10 version 21H2, a universal printer driver compatible with Mopria standards has been integrated and is being enhanced through updates. A phased approach to legacy printer drivers will begin in January 2026, when Windows Update will stop allowing new legacy drivers for Windows 11 and Windows Server 2005. Existing drivers for older printers will continue to function. In July 2026, Windows 11 will prioritize the universal driver over legacy drivers, and by July 2027, updates for legacy drivers will be limited to security fixes. There is no set timeline for the complete discontinuation of old printers and their drivers.

Minecraft’s PS3 source code just leaked with floating islands and early villager houses offering a rare look at scrapped features

The source code for Minecraft's PlayStation 3 version has been leaked online, revealing internal development files and the source code for Minecraft Pocket Edition. This version was optimized for the PlayStation 3's 256MB of RAM and was developed in C++. The leak includes features that were not included in the final release, such as early sky island world generation, prototype waterfall code, and initial designs for villager houses. Enthusiasts have managed to run the PS3 build on PC with functional multiplayer capabilities. The leak may aid researchers in identifying vulnerabilities, although significant security concerns are likely addressed in newer updates. The leak contributes to preservation efforts, allowing the community to explore Minecraft's development during its console era.

Did Windows 10 automatically update itself on this user’s PC with curiously perfect timing — or was this mid-shower surprise just an honest mistake?

Microsoft has been encouraging users to upgrade to Windows 11 since its launch in October 2021, employing tactics such as full-screen pop-up ads. Some users prefer Windows 10 due to its hardware requirements and design issues. A user named 'djseifer' reported that their Windows 10 PC automatically upgraded to Windows 11 while they were away, despite declining previous upgrade prompts. Upon returning, they expressed dissatisfaction with the new interface, particularly the Start menu and centralized taskbar. It is generally understood that Microsoft should not forcibly upgrade a user's operating system without consent, although the user may have inadvertently consented through prior agreements. Users can disable automatic updates to maintain their Windows 10 experience, but this may expose them to security vulnerabilities. Microsoft requires TPM 2.0 for Windows 11, complicating upgrades for unsupported hardware. Windows 10 will still be usable after Microsoft ends support on October 14, 2025, but users will face increased risks from cyber threats. Extended Security Updates (ESU) will provide limited security updates for a time.

With developer verification, Google’s Apple envy threatens to dismantle Android’s open legacy

The F-Droid team published an open letter to Google, supported by 35 organizations, expressing concerns about Google's changes to the Android ecosystem. Many Android users rely on Google for app installations, facing challenges when trying to use alternative app stores or open-source apps without verification. Some developers are shifting to progressive web apps instead of Android. Alternatives to Google's verification system include non-certified Android devices and privacy-focused ROMs like LineageOS or GrapheneOS, but these options come with security vulnerabilities and installation difficulties for most users. Telecom companies impose restrictions on devices to ensure they work on their networks, leading to a reliance on stock software and security updates from Google and manufacturers.

Bootleg Windows, Office scheme crashes, triggers 22-month lockup for Florida woman

A Florida woman, Heidi Richards, 52, was sentenced to 22 months in prison for fraudulently acquiring and selling Microsoft certificate of authenticity (COA) labels in bulk through her company, Trinity Software Distribution. Between 2018 and 2023, she spent over a million dollars on COA labels, primarily for Windows 10 and Microsoft Office products. Richards directed employees to transcribe product activation codes from the COA labels into a spreadsheet, which were then distributed to buyers for software activation. Although the labels were genuine, their procurement and sale were illegal. Following a trial in November 2025, a federal jury found her guilty, and she was also ordered to pay a ,000 fine.

Best Secure and Encrypted Messaging Apps in 2026

Your text messages and calls can be intercepted by hackers, corporations, and government entities, putting your private information at risk. Corporations may use your messages for targeted advertising or sell your data, while hackers may exploit it for identity theft or fraud. Governments may monitor communications under the guise of national security. Secure messaging apps are essential to protect your communications, as many default options expose sensitive information through metadata or lack proper security. Signal is recognized as the most secure messaging app, offering end-to-end encryption, being open-source, and free of charge, though it requires a phone number for registration. Threema allows complete anonymity without data collection but has no free version. Telegram, while popular, has security concerns as not all communications are end-to-end encrypted by default. WhatsApp and Keybase are discouraged due to ownership issues affecting privacy. Characteristics to look for in a secure messaging app include end-to-end encryption, third-party testing, open-source code, self-destructing messages, and minimal user data collection.

PCs under $500 to “disappear by 2028” predicts analyst. Apparently water’s wet, too.

Gartner predicts that the sub-0 entry-level PC segment will disappear by 2028 due to a 130% increase in memory and SSD costs, contributing to a 17% rise in PC prices by 2025. This situation is expected to result in a 10.4% decline in PC shipments this year, the first contraction in over a decade. Consumers are anticipated to keep their devices longer, with business users holding onto PCs for 15% longer and consumers for 20% longer by the end of 2026. The report indicates that elevated RAM and SSD prices will persist longer than expected, influenced by broader inflation trends. Additionally, the anticipated 50% market penetration of AI PCs is now expected to be delayed until 2028.
