Microsoft has some explaining to do. It’s not “just” Chinese consumers who are up in arms about what some are calling forced updates to Windows 10, but a noisy group of U.S. users are also steamed about a change to the update process that they say tried to dupe them into upgrading their older version of Windows.

Earlier this month, Microsoft claimed 300 million devices run Windows 10, but as Fortune noted then, Windows 7 remained the most popular version of the operating system with nearly 48% of the desktop operating system market compared to 15.34% for the less-than-a-year-old Windows 10, according to Netmarketshare,

While this Windows 10 experience is not the one Microsoft public relations wants the world to talk about, the endless-update-cycle is not unique to Microsoft. Some people (raising hand here) find the seemingly endless updates to Apple (aapl) iTunes and OSX to be frustrating.
