Quite a few could not find the drivers for their existing hardware, which forced them to switch back to the way they used their computer before upgrading. Although Microsoft claimed that it works with all the existing computers, reports stated otherwise.
That is certainly an excellent method, given the fact that we all use different gadgets for different needs and at different places. Microsoft changed the direction with Windows 10, and most of the devices running on the platform have seamless connectivity. However, it does require some time to evolve into the best operating system when we compare it with iOS. The Windows 10 is surely a better upgrade over its predecessor.
