Microsoft ships emergency patch to fix Windows 11 installation issues

Microsoft has addressed a significant issue affecting certain Windows 11 systems after the installation of the KB5058405 security update from May 2025. Users reported encountering 0xc0000098 recovery errors linked to ACPI.sys, indicating that the operating system could not be loaded. This problem primarily affects Windows 11 versions 22H2 and 23H2 in enterprise settings, particularly among Azure Virtual Machines, Azure Virtual Desktop, and on-premises virtual machines hosted on platforms like Citrix or Hyper-V. Microsoft has released the KB5062170 non-security out-of-band update to resolve the installation and boot problems, which can be manually installed from the Microsoft Update Catalog. For Azure customers facing difficulties after implementing the May 2025 update, Microsoft recommends using Azure Virtual Machine repair commands as a temporary workaround. Users of Windows Home or Pro editions in home environments are unlikely to encounter these issues.

Windows 11 upgrade block lifted after Safe Exam Browser fix

Microsoft has lifted an upgrade block that prevented certain users of the Safe Exam Browser from installing the Windows 11 2024 Update due to compatibility concerns. The block was initially implemented in September to protect users from issues with Safe Exam Browser version 3.7 or earlier. Users are encouraged to upgrade to Safe Exam Browser version 3.8 or later before proceeding with the Windows 11 24H2 update. If users still encounter the safeguard hold after 48 hours of updating, they should contact Safe Exam Browser Support. The Windows 11 24H2 feature update is now available for all compatible PCs, except those under safeguard holds. Microsoft has resolved issues that previously blocked the update for some users and has removed other compatibility holds for specific devices and applications. However, some upgrade blocks remain due to incompatible hardware and software. Windows 11 24H2 began its rollout in May 2024 for enterprise testing, with a broader release in October.

Windows 11 April security patch quietly blocks 24H2 update, but are you impacted?

Microsoft is preparing to release the Windows 11 25H2 update in October, aimed at facilitating the transition to Windows 11 24H2. However, the rollout of Windows 24H2 has faced issues, with many PCs experiencing blocks due to third-party applications and technical problems. The April security patch, released on April 8, has complicated the upgrade process for some users, particularly those with the patch KB5055528 installed, leading to error code 0x80240069. This issue mainly affects IT administrators using Windows Server Update Services (WSUS), while individual users on Windows 11 Home are largely unaffected. Microsoft is investigating the problem and plans to release a fix by the next Patch Tuesday on May 13. Additionally, organizations are advised to explore alternative update management solutions, as WSUS is no longer under active development.

Microsoft: Windows 11 24H2 updates fail with 0x80240069 errors

Microsoft has acknowledged a significant issue affecting enterprise users trying to upgrade to Windows 11 24H2 via Windows Server Update Services (WSUS) after installing the April 2025 security updates, specifically the monthly security update KB5055528. Users with Windows 11 23H2 or 22H2 are encountering Windows Update Service errors with the code 0x80240069, preventing the download process for Windows 11 24H2 from initiating or completing.

Microsoft acknowledges problem with Windows 11 24H2 update

Windows 11 version 24H2 has been facing rollout challenges due to compatibility issues, leading Microsoft to implement a new block identified by protection number 56318982. The removal of such blocks can take time, similar to the previous ID 52754008 case.

Users attempting to download version 24H2 may encounter error code 0x80240069, attributed to the April 2025 security update (KB5055528). This error obstructs the download process, and there is no temporary workaround available from Microsoft at this time. The issue is also affecting the System Center Configuration Manager (SCCM). Error code 0x80240069 is not documented in Microsoft's resources.

Windows 11 Update Issues and What To Do About Them

Windows 11 version 24H2 has introduced significant issues, including blue screens of death (BSOD) and device bricking associated with update KB5043145. Users have reported problems such as black screens, corrupted boot sectors, and non-functional system restore points. Businesses are facing complications like failed domain join operations, group policy errors, and stalled WSUS updates.
