Microsoft released the KB5062553 update for Windows, which caused boot failures in some Generation 2 Azure Virtual Machines (VMs) with Trusted Launch disabled. In response, Microsoft issued an emergency patch, KB5064489, applicable to Windows 11 and Windows Server 2025, to address these issues. Affected VMs may experience boot failures if Virtualization-Based Security (VBS) is enforced via registry key. Users are advised to check if their VMs are created as “Standard” and if VBS is enabled. The KB5064489 update is not automatically deployed and must be manually downloaded from the Microsoft Update Catalog, with specific installation methods outlined.

Millions of enterprise devices are still using Windows 10, with a report indicating that half of all business-managed Windows devices have not transitioned to Windows 11. In the healthcare sector, 19% of devices are too outdated to upgrade without replacement, and the finance sector also shows slow modernization. The Americas have only 43% of enterprise devices upgraded to Windows 11, while Europe has a 70% upgrade rate. Larger organizations managing over 10,000 devices have completed only 42% of their migrations due to complex environments and aging infrastructure. Microsoft is offering paid support through its Extended Security Updates (ESU) program, and third-party provider 0patch plans to deliver security fixes for at least five years after Microsoft's support ends.

The official end-of-support date for Windows 10 is October 14, 2025, as per Microsoft's Modern Lifecycle Policy. The final version, 22H2, will receive security updates until that date, after which users will not have technical support or security fixes. Users can choose to continue using Windows 10 without upgrades, buy a new PC that meets Windows 11 requirements, switch to a Linux distribution or ChromeOS Flex, pay Microsoft for Extended Security Updates (ESUs), or upgrade incompatible hardware to Windows 11 using documented methods. Microsoft will offer ESUs for Windows 10 at a cost, with reduced rates for educational institutions and higher prices for business customers. Individual consumers can subscribe for continued security updates until October 2026.

Microsoft has acknowledged that the updates released on June 10 during Patch Tuesday may disrupt the Dynamic Host Configuration Protocol (DHCP) service on Windows Server versions 2025, 2022, 2019, and 2016. The DHCP Server service might intermittently stop responding after installing this security update, causing issues for network administrators as clients may be unable to renew their IP addresses. There is currently no viable workaround for affected users other than rolling back the patch, which is not ideal due to the critical security fixes included in the update. The impact of this issue varies among users, with some experiencing significant problems while others report no disruptions. Microsoft is working on a resolution and will provide further information soon. Additionally, Microsoft has faced challenges with its Surface Hub v1 devices, requiring an out-of-band update.

Microsoft's June security update for Windows 11 24H2 introduced critical fixes but was quickly followed by a warning about a compatibility issue affecting a limited number of devices, leading to the throttling of the update. Microsoft plans to release a revised update that will include all security improvements from June 2025. The specifics of the compatibility issue remain unclear, with speculation about potential complications related to various CPU architectures and reports of installation errors from users. The rapid throttling of the patch raises questions about the quality control processes in place at Microsoft.
