A new analysis from Gartner Inc. warns that Microsoft's ubiquitous Windows operating system is on the verge of collapse under its own weight, Daily Tech reports, and that if Microsoft doesn't do something quickly, it's a matter of inevitability that a more able competitor will eventually dethrone it. Gartner's Michael Silver and Neil MacDonald carried out the analysis. The problem, the pair says, stems from Microsoft legacy support, followed by increasing complexity and hardware issues. MacDonald says that Windows is already too bulky and complex, and that simply adding on more complexity will lead to the downfall of the OS.
