Use several Explorer.exe processes to increase stability
5 February 2001 by Snakefoot | Comment » | Trackback OffIt is possible to configure that each Folder-view should get their own Explorer.exe process. Create/update this DWORD in the registry:
Note there exists a different option that will enable Desktop and Taskbar to get their own Explorer.exe process, but this option has several annoying side effects (See below). It is intended to be used when debugging the shell, as one doesn't have to stop and start the desktop and taskbar. Create/update this DWORD in the registry:[HKEY_CURRENT_USER \Software \Microsoft \Windows \CurrentVersion \Explorer]
SeparateProcess = 1 (Default=0)
Matches the setting "Launch folder windows in a separate process" in Folder Options.
Note this option is also required if wanting to launch Explorer.exe with different credentials using RunAs though it is not supported by Microsoft (Another option is just to make a copy of Explorer.exe to ex. Xplorer.exe).

BrowseNewProcess = "Yes"
Matches the setting "Launch browser windows in a separate process" on Advanced-tab in Internet Options. With IE 5.01 it is automatically enabled if having more than 32 MByte RAM.
Note if using Windows XP and having set the value to "No", then Grouping of similar tasks in the taskbar will put Windows Explorer and Internet Explorer in the same group.
