Solution: IE processes not closing down
Are you finding processes left behind by IE8? Sometimes when you close a tab or IE itself it doesnt always shut down the corresponding process.
The IE8 Team have issued a fix:
1. Open regedit
2. navigate to HKCU\Software\Microsoft\Internet Explorer\Main
3. Either create a dword entry called TabShutdownDelay or if its already there edit it (wasnt there on mine)
4. Enter the value (in seconds) you want for how long it takes to shut down the process (0 will force the process to close immediately)
Note: If all IE windows are closed then all processes will be shut down.
