Errata are content issues in published versions of protocols documents that could impact an implementation. Examples of errata are errors or missing information in the normative sections of the technical specifications or in the use cases (examples) in the technical specifications and overview documents.

Content issues that don't impact an implementation, for example, editorial updates due to typos, formatting updates, and rewrites for readability and clarity, are not included in errata.

The following sections list the Windows Protocols technical documents that contain active errata that is not yet released with the documents in the Open Specifications Library. Links to previously published archived errata are available on this page, on the following pages, and on the main landing page of each document, as applicable.

January 2024 Update: Protocols documents will be updated in their Open Specifications Library locations, rather than being published as errata. The following documents with active errata will be republished and their active errata will be archived over the coming months.
