In 2012, Microsoft took a new route with Windows 8 by releasing two versions: a standard version, and another for tablets running ARM-based chips. Microsoft has not released sales figures of either, but reports suggest Windows 8 has not sold well.
However, judging Windows sales is tricky: most people don’t upgrade the operating system alone, but get it when they buy a new PC - which people are doing less often. Even if Windows 8 flops, Microsoft fans need not worry.
The company followed up its last stumble, Vista, with the mighty Windows 7, which was an undeniable success (we still love it). If Windows 8 is the next Vista, expect a follow-up OS to arrive soon to save the day.
