While some users prefer Windows over macOS, we can't deny that Apple's hardware and attention to detail beat all. While officially Apple does not allow you to install Microsoft's desktop operating system on a Mac, we have always been able to install it on the machine via Boot Camp. However, it looks like ARM Macs will not be able to run Windows via Boot Camp.

Tim Cook took the stage at the WWDC 2020 keynote, officially announcing that the company will be moving to its in-house, custom silicon in the future. The transition will take up to two years but we will see the first Mac with ARM-based chip later this year.  The Verge reports that Boot Camp will not run Windows on ARM-based Mac when the machines will be launched. However, it might be possible in the future.
