Windows 10 x64 Education - Black lock screen at system startup RRS feed

  • Question

  • Hello

    We have an issue with the x64 version of Windows 10 Education. The x86 version is working as expected.

    When the x64 version boots, the lock screen is black with the mouse cursor visible. CTRL-ALT-DEL takes you to the login screen. The x64 machine looks like its not on. The only giveaway is the mouse pointer.

    The x86 version shows the correct lock screen with the time on it. CTRL-ALT-DEL takes you to the login screen.

    x86 and x64 machines are on the same domain and share the same GPOs. The image content is the same, just x64 variants of the content for x64 obviously. Settings between the two should be identical.

    We have tried tweaking GPO's but it makes no difference. Changing the personalized background colors of the lock screen indicates the lock screen is trying to work. If you set it to orange, there is a brief flash of orange when pressing CTRL ALT DEL to get to the login screen.  If you change this to purple, a brief flash of purple can be seen for before the login screen loads.

    It seems as if the "image" trying to be displayed on the lock screen is not loading. However it is set to default and those images are present on the machines. The time missing also suggests something graphical going on.

    I have read through various "black screen" articles, they all seem to relate to the pre-release/technical preview versions of windows 10.  Ours is not a pre-release/technical preview version.

    Does any one have any suggestions on what the solution to this issue could be?

  • Hi ScottBowmanDG,

    Does this occur on all of Windows 10 64 bit in your domain? What is the exact gpo you have configured and what is the exact setting you have configured?

    What is exact your machine model?

    Were there any error recorded in Event View when this issue occurred?

    Please run the “gpresult /z > C:\gpresult.log” command to display all available information about Group Policy to verify whether the has been applied successfully.

    There is a lock screen setting in personalization, try to setup lock screen in this setting using the same image content to have a test.

    Best regards
