Windows 11 Lock Screen Glitch: Password Login Icon Vanishes After August Update
Microsoft has warned users of a Windows 11 malfunction: following updates released since August 2025, the lock screen may no longer display the password-login button. The feature itself still works — the icon simply becomes invisible.
As Microsoft explains in its updated support documentation, the issue affects devices that have several authentication methods enabled simultaneously: PIN codes, security keys, passwords, fingerprints, and so forth. Hovering the cursor over the spot where the icon once appeared reveals an invisible active zone. Clicking it opens the password-entry field. For now, there are no workarounds — aside from relying on one’s intuition. Microsoft states that a fix is in progress, though the release date for the patch remains unknown.
This is not the only problem tied to update KB5064081. In September, Microsoft had to address a bug that caused failures when playing DRM-protected video (Blu-ray, DVD, digital TV): the image would freeze, stutter, or turn completely black. That same month, the company resolved additional issues triggered by the August updates — for example, installation failures for applications on non-administrator accounts due to unexpected User Account Control prompts, as well as severe lag and freezing during NDI streaming on both Windows 10 and Windows 11.
Moreover, after the August Patch Tuesday releases, Microsoft was forced to issue urgent supplementary updates to fix an error that prevented security patches from installing through Windows Server Update Services (WSUS), producing error code 0x80240069. Another critical problem was resolved at the same time: a malfunction that broke reset and recovery features on devices running Windows 10 and Windows 10 Enterprise.
