Microsoft's recent optional update, KB5074105, is causing problems for some Windows 11 users despite official claims of no known issues. Shortly after its release, users began documenting malfunctions on support forums. One significant complaint involves integrated laptop cameras failing after the installation.
An affected individual described how their Acer's built-in camera began blinking erratically and failing in applications, signaling a hardware error. Removing the update completely resolved this camera malfunction, confirming its role in causing the problem. Another user experienced a lock screen clock widget that crashes and vanishes within moments of appearing.
A separate comment noted a lengthy one-minute taskbar loading time following a reboot after applying the update. This particular incident may be a temporary post-update glitch rather than a lasting bug. The overall pattern continues a troublesome trend of problematic Windows 11 updates this January.
For those encountering difficulties, the problematic update can be uninstalled via the Windows Update history section. As this is an optional, non-security update, users can safely choose to skip or delay its installation entirely to avoid these complications.
