Windows XP set the bar quite high when it was released back in August 2001. Barring a few security issues, XP was considered a success and is still the OS of choice for some PC users today. Microsoft followed this up with arguably their most criticised offering, Vista. Steve Ballmer, CEO of the Redmond outfit went as far as calling Vista “a work in progress” after its launch. 2009 marked the start of better days for Microsoft, a year in which they released Windows 7, a welcome refresh for PC users. Windows 7 went on to sell an impressive 240 million licences in its first year; a record for Microsoft. Today, in a blog post on Microsoft’s Dutch website, the company explained that it is working on Windows 8, however, the OS will not be due for another two years. Microsoft representatives failed to elaborate further when asked to comment by CNET. According to a leaked presentation earlier this year, Microsoft plans to introduce a native Windows app store akin to Apple’s recently announced Mac app store. Amongst other improvements, Microsoft is purportedly working on improving power efficiency and computer wake times. If you don’t believe in the Mayan calendar, 2012 should be an interesting year for Microsoft. What features are you guys pining to see in Windows 8?
