Comparing to DOS or what? No one runs Win10/11 on FAT now, while NTFS has access permissions and ACLs.

I remember that Win32 apps on Windows 10 and 11 can do whatever they want with the users personal files. Has that changed?

In Win, access to files are controlled by ACL when NTFS is used (dating back to NT 3.1 with NTFS). So it depends on which user runs a process.

Basic hygiene is very simple: never run as Administrator. Create and use a regular user or poweruser group user. It's similar to a regular linux practice. Use Administrator account when needed only.

You can create a separate user, but even a user in the administrators group doesn't have an admin token until elevation.

If you trust yourself to not blindly click OK on every UAC prompt, a single user account in the admin group is fine.

GP is talking about isolation inside the current user. Recent macOS versions ask before allowing a program to access files inside Documents, Desktop, etc. Whether that helps or not is debatable, but it’s not quite the same as what Windows ACLs do out of the box. To achieve the same on Windows, one would have to run the program as a different user to which they’d selectively grant access to the folders inside their profile.

You can enable controlled folders on Windows: https://learn.microsoft.com/en-us/defender-endpoint/controll...

It's not enabled by default, though. Enabling it by default would probably break just about every Windows program out there and like UAC on Vista, everyone would turn it off immediately.

Computer asks for password. I type in password.

Admin access prompts are honestly a joke even on macOS. The source is completely opaque.

Win32 Apps can access anything you can access and also read out some text fields from apps you have running, via accessibility APIs.
