We know that Windows 8 has failed to reignite demand in the PC market so far and now one formerly bullish analyst says that the platform “lacks momentum” and is “challenging” his earlier optimism. Benzinga notes that Bank of America analyst Kash Ragan downgraded Microsoft (MSFT) from “Buy” to “Neutral” on Thursday and expressed dismay that Windows 8 has still shown few signs of catching on “despite more available touch-based devices” more than six months since the platform’s initial launch. Microsoft has been taking feedback from early Windows 8 adopters and is planning to make changes to the operating system aimed at winning over more traditional Windows users with its “Windows Blue update” rumored to be released this summer.
