Booting up Mac OS X in safe mode can solve some troubleshooting issues.
Beginning with Mac OS X version 10.2 and later it is possible to start the operating system in a special mode called "Safe Boot".
To do so you must press the shift key, just after switching on your Mac and holding it down until you see the spinning gear under the gray apple.

Windows XP desktop disappeared
What if one day you turn on your PC and instead of displaying the desktop full of icons you'll just see the wallpaper.
And worse, even rebooting in safe mode has the same result.
Before preparing to reinstall the operating system you can try this.
Bring up task manager pressing Ctrl-Alt-Del. Choose "New task" from the File menu.
Type regedit in the run box and search for the following registry key.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution.options
There should be two subkeys. One named explorer.exe and the other iexplore.exe.
Delete both keys, close the Registry editor and restart the computer.
