The problem I am facing is whenever I start my PC after use login window where it should show the start screen my PC just doesn’t show anything except for a mouse cursor.

I can press CTRL ALT DELETE and go into task manager go into File > Run New Task and then run explorer.exe sometimes this works and start screen becmoes accesible but sometimes I have to repeat it multiple times to make it work or sometimes I just have to restart my PC.

More over while on the black screen and being able to access task manager If I right click processes there and open containing folder that also work I can access all my program/files from there but all that is missing is my desktop and start screen

  • Can anybody help me with this?
  • Plus can anybody tell like for explorer there is explorer.exe is there a .exe file which would start the start screen ?

There's a registry key that tells Windows what "shell" to load on startup. Open regedit, and look for the key here: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

Make sure that the shell key is set to be explorer.exe.

Update: If there is explorer.exe and csrcs.exe, you should delete csrcs.exe from there.

its alread set to explorer.exe – Maven Nov 17 '12 at 21:07

Open your services application using the CTRL ALT DEL + Run method. You should be able to CTRL F to find explorer.exe in there and make sure that it's running state is set to automatic. This way it will automatically boot when you login.

Usually this gets turned off by a virus so I would suggest doing a full scan of your machine using something like malware bytes and a virus checker such as security essentials.

I found that in at least one case, the HKEY_LOCAL_USER one had been modified. So also check:

HKEY_LOCAL_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

There might also be a "Shell" key in there. For my case it was there and had the value of cmd.exe. I changed it to explorer.exe to fix it as stated above.
