Black Screen Isuue in Window 10

Hi kashish,

I would appreciate you for trying troubleshooting steps.

To understand the issue better, I request you to answer few questions:

• Does black screen appear when you before user login’s or after user has logged in ?
  
• Does black screen appears when you lock your pc?

This problem occurs because of a change in the behavior of Win Logon and Logon UI. This change introduces the potential for the deadlock.

I would also suggest you to install all the updates available for the system and check if it helps.

Follow the Below steps:

• Type settings in the Search area on the taskbar and select Settings
• Select Update and Security.
• Click on Windows Update and select Check for Updates

Keep us posted with the status of the issue. We’ll be glad to assist if you need further assistance.

Thank you
