Windows 11 Pro is currently available for .97, which is a 93% discount from Microsoft's standard price of 9. The minimum system requirements for Windows 11 include a 1GHz or faster 64-bit CPU with at least two cores, 4GB of RAM, 64GB of storage, TPM 2.0, and UEFI with Secure Boot. Windows 10 is nearing its end of support, meaning it will no longer receive security updates, which poses risks for users. Windows 11 includes features like BitLocker, Remote Desktop, Group Policy management, and AI-assisted Copilot. Users upgrading from Windows 10 should back up their files and ensure drivers are current. Windows 11 offers performance enhancements for gaming, such as DirectStorage and Auto HDR. Keys priced low are often OEM or volume-license keys tied to a single machine and may not be transferable.

In March, Microsoft released cumulative security updates for Windows 10 and Windows 11, with support for certain versions continuing until March 2026. The updates include KB5079466 for Windows 11 version 26H1, KB5079473 for versions 24H2 and 25H2, KB5078883 for version 23H2, and KB5078885 for Windows 10 version 22H2. These updates will be distributed via Windows Update, the Microsoft Update Catalog, and WSUS for enterprise environments. This month, Microsoft combined the Servicing Stack Update (SSU) with the Latest Cumulative Update, simplifying the update process. Key enhancements include improvements to Secure Boot, with expanded device target data for new certificates, and security enhancements for Explorer’s search functionality in Windows 11 versions 24H2 and 25H2. A fix for Windows Defender Application Control (WDAC) was also implemented, addressing issues with COM objects under certain policy configurations. The Windows System Image Manager received a new warning dialog for confirming the trustworthiness of catalog files, which is important for enterprise environments. Updates for Windows 10 22H2, despite its end-of-life status, included fixes for secure boot issues and improvements for file version history in the Control Panel. An SSU for Windows 11 (KB5077869) was also released to maintain update stability. Microsoft's updates scheduled for March 2026 will address vulnerabilities in components like the Windows App Installer, SQL Server, and Microsoft Office. The Security Update Guide provides detailed information on specific vulnerabilities and affected components.

Microsoft has released the Windows 10 KB5078885 extended security update, which addresses vulnerabilities identified during the March 2026 Patch Tuesday. This update resolves two zero-day vulnerabilities and a critical issue preventing certain devices from shutting down properly. Users of Windows 10 Enterprise LTSC or those in the ESU program can install it via Settings under Windows Update. The update upgrades Windows 10 to build 19045.7058 and Windows 10 Enterprise LTSC 2021 to build 19044.7058. The update focuses on security enhancements and bug fixes, addressing a total of 79 vulnerabilities, including two actively exploited ones. Key fixes include: - A new warning dialog in Windows System Image Manager for confirming trusted catalog files. - Enhancements to File History for backing up files with specific Chinese and Private Use Area characters. - Stability improvements for specific GPU configurations. - Additional high-confidence device targeting data for Secure Boot certificates. - Adjustments to Chinese fonts for compliance with GB18030-2022A standards. - A fix for Secure Launch-capable PCs with Virtual Secure Mode unable to shut down or hibernate after a previous security update. - Resolution of an issue affecting folder renaming with desktop.ini files in File Explorer. The update also addresses a known issue preventing Windows 10 devices from shutting down or hibernating when System Guard Secure Launch is enabled. Microsoft is deploying new Secure Boot certificates to replace those expiring in June 2026, which are crucial for validating boot components and preventing security risks. There are currently no known issues associated with this update.

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.
