August 2025 Patch Tuesday Update Issues for Windows 10 and 11
Recent updates from Microsoft’s August 2025 Patch Tuesday for Windows 10 and Windows 11 have caused a stir in the tech community. While initial reports suggested that NVMe SSDs were encountering severe problems, both Phison and Microsoft have dismissed these claims. Nonetheless, update KB5063878 has been associated with installation challenges, notably generating the 0x80240069 error code during installation.
Impact of the August Patch on User Account Control
Although the Windows 10 August Patch did not initially trigger widespread issues, a newly confirmed problem now affects users of both Windows 10 and Windows 11, alongside server platforms. Microsoft has acknowledged this bug, which is related to User Account Control (UAC).
Following the August 2025 Patch installation, non-administrator users have reported difficulties performing various operations on the operating system. One notable example involves the installation of Office Professional Plus 2010, which fails with “Error 1730 during the configuration process”when attempted as a standard user. This widespread impact suggests that many users could be affected.
Details of the UAC Bug
According to Microsoft, this issue stems from a security patch aimed at resolving a Windows Installer (MSI) authentication vulnerability classified under CVE-2025-50173. The problem is thoroughly documented on Microsoft’s Windows Health dashboard, which outlines the affected scenarios as follows:
….after installing the August 2025 Windows security update and later updates, UAC prompts for administrator rights can appear for standard users in the following scenarios:
- Running MSI repair commands (such as msiexec /fu).
- Launching Autodesk applications, including versions of AutoCAD, Civil 3D, and Inventor CAM, or installing an MSI file after the first user sign-in.
- Installing applications designed for per-user configuration.
- Running Windows Installer during Active Setup.
- Deploying packages via Configuration Manager (ConfigMgr) that depend on user-specific “advertising”configurations.
- Enabling Secure Desktop.
Recommended Workarounds
The proposed workaround for this UAC issue is straightforward: users are advised to run applications with elevated privileges by executing them as an administrator. If this is not feasible, administrators can mitigate the issue through the installation and configuration of a specific Group Policy utilizing Known Issue Rollback (KIR).
