What It Is

dnhash is a hash reference site for historical Microsoft digital delivery files. It emerged in response to the old MSDN subscriber portal being taken offline, after which many non-subscribers could no longer look up MSDN file hashes that had previously been publicly visible. The project aims to preserve this information and let users browse or search it to verify whether Microsoft product files they already possess match Microsoft’s original digital distribution versions. The page states that it has indexed 29263 files.

Core Features and Ecosystem

The site offers Browse, Search, and About sections, with data organized into groups such as All Products, Applications, Business Solutions, Developer Tools, Operating Systems, Servers, and Tools and Resources. Under Developer Tools, it covers a wide range of legacy products, including Visual Studio 2005 through 2017, Visual Studio for Mac, Team Foundation Server, Visual Basic, Visual C++, ASP.NET, Kinect SDK, XNA Game Studio, and Windows Embedded, while also showing file counts and last release dates.

Its value is not in development or build capabilities, but in software supply chain verification and archival validation: if a user already has an ISO or installer, the records on the site can be used to check whether it matches Microsoft’s digital delivery version from the time. The site clearly states that it does not provide any file downloads.

Pricing, Openness, and Integration

The page does not mention fees, accounts, subscriptions, or paid features, so it can essentially be treated as a free lookup site. Open-source status, self-hosting options, APIs/SDKs, and bulk export capabilities are not mentioned. The data comes from external scraping and is updated on an ad hoc basis, so there may be delays before new files appear on the site. Some fields are also not easy to filter, such as x86/x64 architecture.

Pros, Cons, and Who It’s For

Its strengths are a clear focus, rare reference data, broad coverage of older Microsoft developer tools, and an FAQ that clearly defines its role as “reference only, no downloads.” Its drawbacks are unstable update frequency, no guarantee of complete consistency with the Visual Studio Subscriptions portal, and limited suitability for automated integration or large-scale audit workflows.

It is suitable for developers, IT administrators, software asset management staff, and researchers interested in legacy software, especially for verifying historical installation media for Visual Studio, TFS, Windows Embedded, Dynamics, and related products.

Access from China and Alternatives

The crawled page does not provide information about access from mainland China, payment, or CDN usage, so its accessibility status is marked as unknown. Alternatives include Microsoft Visual Studio Subscriptions, Microsoft Evaluation Center, Microsoft Learn download pages, VLSC, and internet archive resources. If official downloads or licensing are required, Microsoft’s official channels should be prioritized; dnhash is better suited as a hash verification reference.
