-Windows: stores PATH in the registry.
+Where is the PATH managed?
 
-Mac & Linux: stores PATH in `~/.config/envman/PATH.sh`
+-   **Windows 10**: stores `PATH` in the registry.

-## Downloads
+Note for **Windows 10** users: due to differences in how `cmd.exe`, PowerShell, and `pathman` use and interpret strings, spaces, paths, and variables, you'll get more consistent results if you:
 
-### MacOS
+-   Use `~` rather than `%USERPROFILE%` or `$Env:USERPROFILE`
+-   Use `/` rather than `\` for delimiting paths
