Thanks again!!

I`m sorry I had not noticed that the text on the picture was in spanish. It says that windows has replaced some damaged clusters in "name" file and "directory". Then, at the end "an unspecified error occurred (75736e6a726e6c2e 4f6)".

I`ll do it and I`ll be updating this thread when I have the report.

Windows 10 black screen and start button flashing

Hi,

Thank you for posting your query at Microsoft community.

If you see the black screen only after sign-in
and you can see a mouse cursor:

• Is it a notebook or tablet? Try using hardware buttons to adjust display brightness up,
  
• While at the black screen, try using CTRL+SHIFT+ESC to start Task Manager.
• If it becomes visible, try finding LockAppHost.exe on the Details tab and ending the task.
  

• If this resolves the black screen, use corruption resolution steps (dism, then sfc), and run the all apps
  

Press Windows+X.


Click on Command Prompt (Admin).

• 
  Type the command DISM.exe /Online /Cleanup-image /Restorehealth
  and hit Enter.
  

PowerShell command:

• Get-AppXPackage -AllUsers |Where-Object {$_.InstallLocation -like "*SystemApps*"} | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
  

If this does not work, then Explorer.exe probably crashed. you can start Internet Explorer to achieve an LMI connection to then perform some other troubleshooting:

• In Task Manager, File, Run. iexplore.exe
• Once you achieve a connection you can use a few tools started from Task Manager to make progress:
  
• Appwiz.cpl: Look for Antivirus software or other apps that may cause issues with the shell. Uninstall them. Then restart.
  
• Compmgmt.msc: This is Computer Management, where you can find the Event Viewer to search for details on an Explorer.exe error.
  
• CMD started as Admin: Use this for various commands, like creating a new administrator user with the following commands (changing “<password>” to something of the customer’s choosing):
  
  net user test <password> /add
  
  net localgroup Administrators test /add
  
  This will give you a test user to try, which will confirm if the issue is user or system-specific.

Please let us know how it goes.
