Before every Windows release there are articles about the reluctance of business user to adopt the new OS. Often they are correct, as businesses like to test the new Windows thoroughly.
With Windows 10, though, I believe it is different scenario, as many business did not jump on the Windows 8/8.1 upgrade cycle and are thus more eager to move to Windows 10.
Now a new survey was published that show rather positive numbers. It’s likely that the true outcome is somewhere in between, but I expect Windows 10 to do well.
