Try this for your systems that arent too fast
Edit your registry for:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Explorer\BrowseNewProcess]
"BrowseNewProcess"="no"

Now when launching IE, a new thread will be created in explorer.exe instead of creating a new Iexplore.exe process.

I suppose this can save some resources on memory deprived systems...
