Since its launch in October, Windows 11 24H2 has faced a myriad of challenges, including network connectivity issues, malfunctioning keyboard shortcuts, and crashing Office applications. For many users, the only viable solution has been to revert to an earlier version of Windows 11.
In an effort to address these concerns, Microsoft recently rolled out cumulative update KB5046617, aimed at enhancing stability and rectifying bugs within the 24H2 version. However, this update has inadvertently led to new frustrations, as users are encountering difficulties during the installation process, often met with various error messages devoid of clear explanations.
The problem with patch KB5046617
Users attempting to install the cumulative update KB5046617 may experience issues at different stages of the process. Reports indicate that error codes such as 0x800f0991 or 0x800f0922 can appear when the installation reaches approximately 35 to 40 percent completion.
In some cases, the update may seem to install successfully, only for the Windows Update section in Settings to indicate a failure. This lack of clarity regarding the reasons for the failure complicates troubleshooting efforts significantly.
To compound the situation, Windows 11 persistently attempts to install the update even after a failure, creating a frustrating cycle for users.
What you can do if you’re affected
Fortunately, there is a workaround for those struggling with the installation of the KB5046617 patch. Users can try to install the update manually rather than relying on Windows Update.
To proceed with a manual installation, follow these steps:
- Open the Microsoft Update Catalog in your web browser.
- Search for
KB5046617. - Locate the correct version for your system and click the Download button.
- When prompted, select the appropriate link to download the installer file.
- Double-click the downloaded file to initiate the installation — it should complete without any error messages.
If you continue to face issues with the installation, the only recourse may be to wait for Microsoft to resolve the underlying error. As of now, there is no indication of when a fix might be released.
