Microsoft has warned users of a Windows 11 glitch: after the release of updates starting in August 2025 , the password-based sign-in button may disappear from the lock screen. While the feature itself still works, the icon simply becomes invisible.
As Microsoft explained in its updated guide, the issue affects devices with multiple sign-in methods enabled: PIN, security key, password, fingerprint, etc. Hovering your mouse over the icon’s previous location displays an invisible hotspot . Clicking it opens the password entry field. There are currently no workarounds other than relying on your intuition. Microsoft has stated that it is working on a fix, but a release date is unknown.
This isn’t the only issue with the KB5064081 update. In September, Microsoft fixed a bug that caused crashes when playing DRM-protected videos (Blu-ray, DVD, digital TV), resulting in frozen, choppy, or even black images.
That same month, the company also fixed other issues caused by the August updates, such as app installation failures for non-administrator users (due to an unexpected User Account Control prompt), as well as severe lags and freezes when streaming via NDI on Windows 10 and 11.
Additionally, after the August “Patch Tuesday” push, Microsoft was forced to urgently release additional patches to fix a bug that prevented the installation of security updates through Windows Server Update Services (WSUS), with error code 0x80240069.
At the same time, another serious issue has also been resolved: a technical issue prevented the system restore and reset functions from working on devices running Windows 10 and Windows 10 Enterprise.
