Limiting the damage when Explorer crashes.


Often, Windows Explorer freeze,the taskbar and desktop also become unresponsive, as all of them are managed by the system through the same process.


  • There is a possibility of isolating the desktop and taskbar in another process (independent) so that both stays operational despite the crash of Explorer.
  • Go to Start and Run, and type regedit.
  • Expand HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer
  • Select the DesktopProcess key and give it the value 1.
  • If you do not have this key, create a DWORD value of 32 bits with the New command (right click in a blank space) Name it DesktopProcess
  • Restart your pc.
  • This change brings a slight increase in occupied space in memory.
