At present, it is possible to run Windows on an Intel Mac either through Boot Camp in Utilities or through virtualisation software like Parallels, VMWare or Virtual Box.
At the keynote on Monday mention was made of this being present when Apple Silicon computers are released. No mention was made of Windows, however, but Linux was mentioned as being able to run.
This suggests that if you want to continue to run Windows on a Mac, you may need to stay with Intel based Macs unless the virtualisation software companies catch up and release Apple Silicon versions of their software. Microsoft would have to agree too.
Update: You will NOT be able to run Windows on a new Apple Silicon Mac when they are released.
