Microsoft has been doing quite a bit to improve some of the more obnoxious portions of an operating system as they work on Windows 8 and it would seem that they’ve fixated their gaze on little old chkdsk. Users rarely run into situations that require chkdsk’s intervention but when they do they’re in for quite the lengthy wait as it looks over your hard drive for faults. It wasn’t a huge issue when hard drives had small capacities but with larger drives on the market you can imagine that you won’t have access to your PC any time soon. The updates they’re implementing seem to allow for better detection of issues while you’re using your PC so you don’t have to run pesky scans manually and it only requires a reboot to fix issues it has found on the OS drive. The fewer the annoyances the better.
