Whenever I try to start my computer, nothing is displayed on the screen (just the background wallpaper, but no Start bar or desktop icons). By opening the Task Manager I see explorer.exe is not being executed, and I'm not able to use the run command to open it. It seems the file is permanently damaged. The only way I can navigate the Internet is by using Safe Mode with networking (as I'm doing right now), but in Safe Mode I'm not able to install new programs (and I need certain specific software for an online job interview tomorrow).

Is there any way I can repair explorer.exe? I've already tried making a copy of it, pasting it in the same C:\WINDOWS folder (but with a different file name, i.e. chicken.exe) and modifying the shell file in the Registry editor in order to run that new chicken.exe file. Doing so I'm able to reboot my computer and enter Windows normally (out of Safe Mode). All the desktop icons are displayed and the Start bar as well (but it's the old Start bar, not the Windows XP one), but I have no wireless Internet connection and I'm not able to open Internet Explorer or Mozilla Firefox. Any idea? My HijackThis records:

Although this thread dates back to June 11, 2010, just for future users who may experience the same problem.

The Hyjackthis report is clear. The system was gravely infected by a trojan horse and needed to be cleaned using Malwarebyte after deleting several registry entries using Hyjackthis.

End of story

A program called explorer.exe controls the display of your taskbar and desktop icons. If for some reason it goes missing (you may have killed it using Task Manager, for example, or something more sinister like a virus has deleted it from your processes), then try this first:

1. Open Task Manager (press Ctrl+Alt+Del, then click Task Manager).
2. On the Applications tab, click New Task at the bottom right of the window.
3. Type explorer.exe, then click OK.

If nothing sinister caused it to disappear, it should all come back as it was and you can stop panicking, breathe a sigh of relief, and continue working.

If that doesn't work, then try this:

1. Open Task Manager (press Ctrl+Alt+Del, then click Task Manager).
2. Go to the Processes tab.
3. Click on the Image Name column header to sort the list alphabetically.
4. Find all explorer.exe processes -- select each, then click End Process for each one.
5. On the Applications tab, click New Task at the bottom right of the window.
6. Type explorer.exe, then click OK.

There's no process named explorer.exe; and, as I've told you before, I'm not able to run it by using the Task Manager run command. And there's no explorer.exe folder in the Registry editor.
Same problem. Explorer is no where to be found. Everyones
"solution" that I read entails deleting explorer.exe at some point in some
way. However, I obviously am unable to do this. Please help......
the run explorer.exe works but its not permanent. everytime I logon I have to do this. please help

Delete explorer.exe folder and restart your pc
