Of course, but most if not all of the binaries on the system will be 64bit. Someone just starting out may struggle to find a 32 bit binary.

Your comment suggests that you don't work on a Windows PC very often: it is the common situation to find quite many older applications on the PC that are 32 bit. Just to give one example: until Visual Studio 2019, Visual Studio was still a 32 bit application.

Actually, there even today exist quite some vocal Windows users who would love to run some really old 16 bit applications on their 64 bit Windows PC (but Microsoft stopped supporting running 16 bit binaries on 64 bit Windows versions).

These are not mutually exclusive positions, but afaik visual studio isn't part of the os. As another commenter mentioned, the builds are all 64bit as well. Sure you can always find a 32bit app to install, but the point is a beginner may not do that and be disappointed when the registers they see on their machine don't match what they read about.

Especially in today's hardware (/software?), all the bins on the system are 64bit even if it's a 32bit binary, the remaining bits get filled by 0s so that the system treats it as a 64bit bin.
