Is Windows 10 Home More Secure Than Windows 10 Pro?
It’s true that Home has reduced attack surface compared to Pro. On the other hand, those features of Pro are optional (e.g. you can easily disable the remote desktop protocol server). However, it’s also harder to secure Home edition well, in some ways. It doesn’t have some features like Encrypting File System or user-controllable BitLocker, it’s possible to modify ACLs on files but it’s missing the advanced GUI for doing so, and it doesn’t have a lot of the UI for manipulating Windows security policies such as most advanced changes to user capabilities (it’s missing secpol.msc, the Local Security Policy editor, and also the Group Policy Editor). Technically many of those settings are still present in Home; you just have to know far more about the Windows Registry than any sane person would.
For a user who isn’t ever going to mess with advanced firewall rules or change any security settings beyond moving UAC between its four options exposed in the Control Panel, Home is fine, and maybe ideal. For people who want to require a boot-time passphrase for BitLocker and control which users are allowed to create symlinks, you want a higher edition.
