Windows 11 24H2 is facing significant installation issues, particularly with the recent KB5046617 Patch Tuesday update. Many users report being unable to install the update due to device-specific bugs, especially on ASUS PCs and systems with fingerprint scanners.
For those who managed to install, the experience has been marred by new problems stemming from a previous update intended to fix bugs. Users have encountered installation failures, often getting stuck at 30-40% or 95%, with error codes 0x800f0991 and 0x800f0922 providing little clarity on the failures.
Some users report that even when installation appears to complete, the update fails without an error code. Deleting Windows 11 cache files leads to another error code: 0x80070003, and troubleshooting tools like DISM and SFC have proven ineffective.
Microsoft has yet to address these issues officially, and no mention of the installation problems appears in their 'Known issues' section. An alternative method for users is to manually download the .msu installation file from the Microsoft Update Catalog, which may allow for a successful installation.
If problems persist, users may consider an in-place installation via Microsoft's Media Creation Tool or wait for an official fix while pausing updates to avoid repeated error encounters.
