Do not specify a particular version unless it is necessary for the context. For example, you may need to specify the version number when comparing current and previous versions of the same product or for reasons of clarity and technical accuracy. Do not include the update identifier of a product unless it is technically relevant.

If you must mention a version number, specify it on first mention in a topic or section. Thereafter, refer only to the product name without the version identifier. For products whose original release identifier includes .0, use .x (in italic type) to indicate all release numbers of a product.

You may use earlier if the statement is accurate for all preceding releases. For example, you can use “Windows 2000 or earlier” as long as the statement is accurate for all preceding releases, including Windows 1.0.

Do not use later.
