Although its too early to confirm that Microsoft has achieved all of their goals, it appears they're on the right track. Windows 8 has generally been an improvement over Windows 7 on the few systems we've installed the RTM release on: they boot up and shut down quicker, for example, and overall performance seems faster. This makes sense, because the new OS is built to boot and shut down faster than previous editions, use less memory and disk space, consume fewer combined processor and GPU resources, and accommodate a wider range of devices and screen sizes.
The Windows 8 file manager, task manager, and even the setup process itself has been optimized; the ultimate goal for these improvements is to enhance performance and minimize resource consumption, which in turn would lower power consumption and potentially improve battery life on laptops, tablets and other mobile devices. So while it's not terribly expensive to build a new PC tuned for Windows 8 (check out our guide to ) you might want to try installing it on your old PC first and implementing a few of the tricks and tweaks we've learned from testing Microsoft's latest operating system.
While Windows 8 is designed to be installed on cutting edge technology, it was also engineered to work well on lower-performing hardware. In fact, Windows 8s system requirements are barely any higher than Windows Vistas, which was released almost six years ago.
According to Microsoft, Window 8s hardware requirements are:
If youd like to take advantage of some of Windows 8s ancillary features and capabilities, these additional items will also be required:
