It's a hive in the Windows registry and the equivalent of `~/.*` in 
Linux terms (HKEY_LOCAL_MACHINE[/Software] being the equivalent of 
`/etc`). The fact that you're asking indicates that you should read 
about that in advance. 

The task itself is definitely not that hard. Maybe someone has 
already asked at StackOverflow. But the devil's in the detail.

Some things to consider

- Python is not by default installed on Windows, so you have to use a 
way to run your script without (PyInstaller for instance).

- by default there is no entry in HKCU, so you have to create it 
first (under HKEY_CURRENT_USER\Environment).

- you need to create the correct type (REG_SZ, null-terminated 
string)

- Windows paths are semicolon separated (not colon).

- Windows only module for the Registry:
