Explorer.exe is not starting automatically when I boot (Windows 10) RRS feed

  • Question

  • When I start my laptop it goes to a black screen with a small command prompt window. I have to use CTRL-ALT-DELETE to open the task manager and run explorer.exe as a new task. This happens in safe mode as well. I have checked HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon in the registry editor and "shell" only shows "explorer.exe" there are no other values listed. Running sfc /scannow does not fix the problem; it reads "windows resource  protection did not find any integrity violations" upon completion. How can I fix this?

  • Hi,

    The Shell registry entry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon should only be explorer.exe

    Have you tried running the following?
    Dism /Online /Cleanup-Image /RestoreHealth


    Let us know if it helps!

    Kind regards,
    Leon

  • I have this same issue. The registry has the correct entry for ... explorer.exe  ... I have checked the environment variables and they have the correct paths.  Windows just starts with a black screen with the command prompt. If I type in explorer it all then works. I do not want to this every time I log in. 

    I decided to create a new admin user and that starts correctly. So the problem is with the user account. I could use the new account but that is a fudge I would really like to resolve the problem if anyone can help.

  • Looks like something is corrupted with one of your user profiles.

    You could also try the suggestions in the link below (even if it's for win7):

  • I found that you might need to also go to HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Winlogon, then delete shell

    So, overall, make sure in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon shell is set to explorer.exe
    In HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Winlogon, The shell registry entry is removed entirely, and in HKEY_CURRENT_USER\Software\Microsoft\Command Processor, remove Autorun if it exists

    Also, check to make sure that you don't have some malware in C:\Users\your username\AppData\Roaming\Microsoft\SoundModule\SoundModule.exe. I do not know if there's a legitimate "SoundModule.exe" but I know that the one that was on my drive was malicious.

    Good luck

  • In HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Winlogon, The shell registry entry is removed entirely

    Mine was set to %comspec%, removed that in hope that it will help.
    Otherwise I need to type "explorer" in the cmd on boot.. It's getting seriously annoying.

    EDIT: That one reg key solved my issue. Thanks mate.

    This is the same thing, so you might want to remove those other entries/files. 

    from reddit user spiralspectra: (Just replace "soundmixer" with whatever your virus called itself)

    Mate i fixed it, it seemed like a virus:

    Here is a step by step on how to do away with these.

    1.a) Open Run (windows key + r) and enter "%appdata%" without quotes and press enter.

    1.b) Go to the Microsoft folder and delete the SoundMixer folder contained within (This is the mining software).

    1.c) Open Run and enter "regedit.exe" without quotes.

    1.d) Find the registry entry mentioned as([HKEY_CURRENT_USER\Software\Microsoft\Command Processor]) and remove it. This entry attempts to run the miner whenever a CMD is started.

    2.a) Go to the winlogon registry entry in the same regedit software ([HKEY_CURRENT_USER\Software\Microsoft\WindowsNT\CurrentVersion\Winlogon])

    2.b) Check the sub-key named "shell" and change its value to "explorer.exe" without the quotes. (This means when you log onto windows it will no longer attempt to run the miner and instead start up normally.)
