tox 4.61.3 (tox-dev/tox#4060) treats single-quoted command text as literal on Windows, so python -c 'print("{env_python}")' now hands Python a "C:\Users..." literal and fails with a unicodeescape SyntaxError. Pass the path as a double-quoted argument instead.

Windows commands now preserve the leading backslashes in UNC and extended-length paths, including quoted paths and
--source=\\server\shareoption values.Track quotes while preparing arguments for shlex. Preserve single-quoted text and keep existing escapes for interior or bare backslash pairs. The reference docs include a quoted UNC path example and explain the escaping rules.
