Open Folders In A New Process

By default Windows 7 opens folders in the same process. This saves system resources, but means one folder crash can bring down the entire shell. If your system seems unstable, or you're doing something in Explorer that regularly seems to causes crashes, you can open My Computer, hold down the Shift key, right-click on your drive and select 'Open in New Process'. The folder will now be launched in a separate process, and a crash is less likely to affect any other open folders.
