Microsoft: Windows bug blocks Microsoft 365 desktop app installs

Microsoft is addressing an issue preventing users from installing Microsoft 365 desktop applications on Windows devices due to misconfigured authentication components. The affected versions are Microsoft 365 desktop apps version 2508 (Build 19127.20358) and version 2507 (Build 19029.20294). Microsoft is working on reconfiguring the authentication components, with a resolution expected to be deployed soon. The issue has been classified as incident OP1186186, indicating a critical service disruption. Additionally, another problem, tracked as MO1176905, is affecting some admins and users by restricting access to various Microsoft 365 services due to a misconfiguration related to Microsoft 365 Group SecurityEnabled settings. Recently, Microsoft resolved a bug related to Microsoft Intune and mitigated a DNS outage that affected global customers.

Microsoft patch Tuesday update fails to install

Microsoft has acknowledged an issue with its August Patch Tuesday update affecting installations via Windows Server Update Services (WSUS), specifically that the "August 12, 2025 Windows security update for Windows 11, version 24H2, might fail to install with error code 0x80240069 when installed via WSUS." This error complicates update management for organizations using WSUS. Microsoft is working on a resolution for this issue, which will be included in a future Windows update. Administrators can manually install the patch or use a provided group policy as a workaround. There is currently no timeline for when the installation issue will be resolved.

Microsoft reiterates it may never truly be able to fix Windows Update 0x80070643 error

In April, Microsoft released dynamic updates for Windows 10, including KB5057589, which was intended for the Windows Recovery Environment (WinRE). Users faced issues with the 0x80070643 error code despite having sufficient disk space. Microsoft decided not to reoffer this update to users who installed it and promised a more reliable update. In July 2025, Microsoft released a new WinRE update, KB5063523, which automatically applies the Safe OS Dynamic Update (KB5062691) to enhance recovery features. This update resolves the previous installation issue, although the error code may still appear. Additional dynamic updates released on July 8, 2025, include KB5062682, KB5062787, KB5062788, KB5062691, KB5062689, and KB5062692, all aimed at improving Windows setup and recovery environments. These updates will be automatically downloaded and installed via Windows Update.

Microsoft confirms Windows 11 KB5044284 / KB5046617 can’t install new updates

Microsoft has acknowledged an issue affecting users of Windows 11 version 24H2 who installed the OS using external media like CDs or USB drives. Users may be unable to install security updates released during the October 2024 (KB5044284) and November 2024 (KB5046617) Patch Tuesdays if they used external media for installation. This issue does not affect installations via Windows Update or the Update Catalog. The problem arises when the installation media includes the October or November security updates. Microsoft recommends avoiding installations with these updates and instead using media that includes the December 2024 monthly security update or later. Microsoft is investigating the issue and will provide further updates.
