Six awesome built-in Windows 8 utilities no one knows about | PCWorld

If you poke deep inside the new Win 8 Pro OS, you'll find a generous assortment of software tools, many of which make third-party utilities redundant.

One built-in tool helps you calibrate your PC’s display. Another helps you investigate system-stability problems. And yet another lets you record on-screen actions to create tutorials for Windows applications. All of these utilities are free and come preloaded in Windows 8, with no hidden add-on costs. (You should be aware, though, that the Hyper-V virtual machine manager requires Windows 8 Pro or Enterprise, not the standard version of Windows 8.)
