gh-148488: Clarify that both / and \ slashes are accepted in py -V:company/tag

[Jah-yee]

Good day

This PR addresses issue #148488, which reported that the documentation for py -V was confusing regarding which slash characters are accepted as separators between company and tag.

Changes

In Doc/using/windows.rst, the sentence:

This should be separated from the tag by a slash, and may be a prefix.

was updated to:

This should be separated from the tag by a slash (either ``/`` or ``\\``, both are accepted on Windows), and may be a prefix.

This makes it clear that both forward slash / and backslash \\ are accepted as separators on Windows (as the underlying implementation handles both), resolving the confusion noted in the issue where the example used \\ but the text only mentioned "slash".

Verification

• Documentation builds cleanly with Sphinx (no warnings related to this change)
• The change is minimal and targeted, affecting only one sentence
• Both example entries (Distributor\\1.0 and distrib/) already exist in the file, confirming both slash types are intended to be demonstrated

Thank you for your attention. If there are any issues or suggestions, please leave a comment and I will address them promptly.

Warmly,
Jah-yee
