There’s not much to learn in Windows land! Learn how to set file permissions, how the registry works (and some important settings that use it), and how Active Directory works (it’s LDAP) and you’ll be fine.
If you’re used to using Linux nothing will frustrate you more than being forced to use a Windows desktop. The stuff you use every day just isn’t there. You can add on lots of 3rd party tools to make it better but it’ll never measure up.
When you have to go out on the Internet to download endless amounts of 3rd party tools the security alarms in your head might start going off. Windows users have just learned over time to ignore them 🤣
