Windows 11 24H2, launched in October, has encountered issues such as network connectivity problems, malfunctioning keyboard shortcuts, and crashing Office applications, prompting some users to revert to earlier versions. Microsoft released cumulative update KB5046617 to improve stability and fix bugs, but users have faced installation difficulties, receiving error codes like 0x800f0991 or 0x800f0922 during the process. Even when the update appears to install successfully, it may still show a failure in the Windows Update section. Windows 11 continues to attempt the update despite failures, causing frustration. A workaround involves manually installing the update through the Microsoft Update Catalog. If issues persist, users may need to wait for Microsoft to address the errors, with no timeline for a fix currently available.
