how you can get around the Windows 8 Metro UI and have your standard Windows 7-styled user interface back

Since the Windows 8 beta versions are online, most of you will be delighted with the welcoming user interface of the built-in Metro UI. However, the tiled interface, which is basically built with a touchscreenmonitor in mind, can be very irritating when used with a conventional mouse. Just imagine swiping the initial screen upwards with your mouse and subsequently typing in your password to log in, and later looking at the whole desktop flooded with tiles and apps. Although it may look nice for a while, it tends to get frustrating after a bit because you're so used to the desktop interface that's been around ever since Windows 95 introduced it.
In this workshop, we show you how you can disable and re-enable the Metro UI with ease. All it takes is a simple tweaking utility, and you are back in action, using your old mouse on a Windows 7-styled UI. You will need a utility called ‘Windows Eight Metro UI Switcher’, which can be downloaded from SuperUtils.com. The utility is less than 1 MB in size and is portable. It will also help you get back the classic Task Manager that displays processor utilization. Using the tweaking utility also disables the Ribbon interface, which can be turned on whenever needed. All changes are eff ective only after a system restart or a user log-off . The utility does not need any administrator privileges for tweaking and runs on both x86 and x64 versions of the Windows 8 operating systems. The utility is standalone and needs no runtime libraries or .NET framework for running. And best of all, it is freeware. Simply start the utility, disable/enable the Metro UI and restart the PC. Your Metro UI is all gone.For those who do not want to use the utility and do it manually, you can use two other methods. The fi rst method involves tweaking a registry key. Start the registry editor and scroll down to‘HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer’. On the right side, you will find the string ‘RPEnabled’ - change its value from ‘1’ to ‘0’. Close the registry editor and restart the PC. To enable it again, simply revert the value to ‘1’. The other method involves renaming a system file in the Windows folder. Start the Windows explorer and hunt down the fi le named ‘shsxs.dll’ and rename it to something else, for example, ‘shsxs.dll.backup’. Now in order to change the fi le’s name, you will need to take ownership of the fi le before you rename it. After renaming it, simply restart the PC, and you will be back to the good old Windows 7-styled user interface
