This will further secure your windows explorer from crash though not a great idea if short on memory. Open registry by going to START-RUN and entering regedit. Navigate to [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced] . In this look for value of "SeparateProcess". If available set its value to 1 and if not (which could be the case ) then add a DWORD key by the name "SeparateProcess" and set its value to 1.If you would rather prefer not to change registry settings , you can get similar results by following steps mentioned below Click on "Start" Menu Clcik "My Computer"Click on "Tools" MenuClick "Folder Options" Check "Lauch folder windows in separate process"Stability would be more because each Folder window will start in separate process and will not cause system to halt in case one or more of such processes stop responding. Although it is supposed to provide better stability but may be at the cost of performance.
