About Release Index

Records

1,735

A hash lets you check whether the file you downloaded matches the record in this catalogue.

If the hashes match, that shows your file agrees with the value that was recorded. It is useful for catching a truncated download, a corrupted file or the wrong file.

A matching hash does not prove the file is genuine or safe. MD5 and SHA-1 are also legacy algorithms and should not be treated as absolute proof of authenticity.

The hash checker runs directly in your browser. Your file is not uploaded to any server. Open the hash checker

Not every source provides complete data, so some records may be missing:

• File size: shown as Not listed when the source does not provide it.
• Release date: sometimes only determinable by month or year from the release label.
• Language: in some cases inferred from the filename.

Release Index prefers to show the data it actually holds rather than guess at what is missing.

Release Index is an independent website, not owned or sponsored by Microsoft. Windows, Windows Server, Microsoft Office, SQL Server and related trademarks belong to their respective owners.

A version appearing in this catalogue does not mean you hold a licence to use it. Software that requires a licence must be activated and used with a valid one.

No public contact method for record corrections or removal requests is currently available.
