The "launch browser windows in a separate process" option was available on the advanced tab in versions of internet explorer earlier than version 5.01. After that, this option isn't available any more in internet explorer 5.01 or 5.5. By using this tweak you can setup this option even in later versions. For this, go to start > run menu, enter regedit and navigate to the registry path listed below. If the subkey \browsenewprocess does not exist, create it as explained below. Then, create a string value browsenewprocess in the right panel. Now, right-click and modify its value to yes for launching browser windows in a separate process, or no for not launching separate process. The changes take effect after a restart or logoff. When editing the registry it is highly recommended to run a quick scan for optimization, you can test your system now for free.
