Windows stuck on lock screen – no password box appears

Dear Microsoft Support Team,

I’m experiencing an issue with my Windows computer where it occasionally gets stuck on the lock screen after waking from sleep mode. The lock screen background image appears normally, but the password/PIN input box does not show up, so I cannot sign in.

When this happens, I try clicking the mouse repeatedly and pressing the Space key on the lock screen, but nothing appears and there is no response. The only way to recover is by restarting the computer.

After force restarting, everything works normally again. However, the issue sometimes occurs again when the system wakes from sleep.

Could you please advise me on how to fix this issue or provide steps to restore the sign-in screen when this happens?

System details:

Device: Laptop

Operating System: Windows 11 25H2 (26200.8037)

If you need any additional information (logs, screenshots, system version, etc.), please let me know and I will provide them.

Thank you for your support.

Best regards,

Loc Huynh Phuoc

    Open the Settings App.

    Go to System - Recovery.

    Click the Reinstall Now' button in the 'Fix problems with Windows Updates' section, then wait for that process to complete.

    This process should fix any corruption in the Windows system, and this process will not affect your files, settings or installed apps.

    The described behavior matches a known class of lock‑screen/sign‑in issues where the lock screen appears but does not respond to input or show credentials.

    Based on the available information, the following actions are supported:

    1. Install the latest cumulative update for the build
    • Similar lock‑screen/sign‑in issues have been fixed by Windows updates in the past. For example, a deadlock between WinLogon and LogonUI caused a black/blank lock screen that did not respond to keyboard or swipe actions in Windows 10 Technical Preview build 9879, and it was resolved by installing an update via Windows Update.
    • On the affected device, run Windows Update and install all available quality and cumulative updates, then restart the device.
    1. Fully restart after updates
    • After installing updates, a full restart is required for fixes to apply correctly to WinLogon/LogonUI components.
    • Use Start → Power → Restart (not Shut down) after updates complete.
    1. If the issue persists after updating
    • Because similar symptoms have been confirmed as product bugs in earlier builds and fixed only via updates, if the device is fully updated and the issue continues, collect details (exact build number, frequency, and any pattern around sleep/wake) and contact support with that information so it can be investigated as a potential bug in the current build.

    When the problem occurs, if the system does not respond to keyboard or mouse at all and no password box appears, the only supported recovery step in the provided information is to restart the device, as already being done.
