I do the same thing on Linux. I have multiple different users I use for various purposes. One for Work, Personal, Side Business, and an emergency "break glass" user.

I install most applications in my home XDG directory if possible. It helps me have pure separation between work and home life. If I'm on my personal user, I do not have access to work tools, etc.

If you're already going to these lengths to compartmentalize, you might as well just run Qubes. It's really not much more mental overhead.

Plus you get nice features like different color window borders for applications running in different profiles, properly permissioned inter-profile RPC, virtualized networking ('personal' gets networking from clearnet 'sys-firewall', 'work' gets networking from 'work-vpn', 'project1' gets networking over Tor from 'sys-whonix', etc.), and much, much more.

Highly recommended way to use any flavor of windows going back to way back when - give your admin account a long fancy password and then just rarely logon as that account. Your daily driver is an account with normal priviliges. Also good for Grandma so she can't install a bunch of spyware

Good until your Grandma calls you because some software require the admin password.

Or not worry about Granada at all

Windows now exposes the multiple desktops feature in the shell.
