It seems that Microsoft is developing a pattern lately. After a flood of good news comes the fine print and some sad, if not worrying, follow ups. First it was the speculation that the lure of a free Windows 10 upgrade for pirated copies of Windows might not be so sweet after all. Now it seems that Microsoft will potentially ostracize another group of computer users: those who dual boot operating systems. Slides from its presentation in China seem to hint that Microsoft won't block OEM's from prohibiting users from disabling secure boot.
