Hello, thank you for report.
Actually, HOME variable doesn't exist in Windows by default. Instead it has HOMEPATH and USERPROFILE (contains the same value).
We will consider adding variable for consistency or updating documentation

Hello, we wouldn't like to add new variable to Windows environments. We will update documentation to avoid confusing.
