WINS is Dead: Microsoft to Fully Retire WINS Name Resolution from Windows Server Post-2025

Microsoft routinely retires certain features or components from the Windows SKU, typically due to security concerns, declining usage, or the emergence of superior alternatives. Now, the WINS name-resolution service is set to be fully and permanently deprecated.

WINS — Windows Internet Name Service — was first introduced in 1994 with Windows NT 3.5. Over time, its user base has dwindled dramatically, as modern networks no longer rely on WINS for name resolution.

In its place, today’s internet infrastructure depends primarily on the Domain Name System (DNS), prompting more and more enterprises to abandon WINS entirely. Microsoft announced the deprecation of WINS with the release of Windows Server 2022, and has now published a blog outlining the service’s long-term future.
Because the service is obsolete, it was deprecated starting with Windows Server 2022; Windows Server 2025 will still support it, but only as the final version to do so. Beyond that release, WINS will be removed from Windows Server altogether.

According to the product’s fixed lifecycle, future iterations of Windows Server will not include WINS, yet existing WINS deployments will continue to receive support until November 2034. After that date, Microsoft will cease providing all security updates and bug fixes.

In practice, WINS has already entered a maintenance-only state: Microsoft no longer develops new features and offers only basic support. Its fixed lifecycle aligns with that of Windows Server 2025, meaning both WINS and Windows Server 2025 will reach end of support in November 2034.

Microsoft believes that giving enterprises a decade of advance notice will help them complete their migration from WINS to DNS in a timely manner. The company also underscores DNS’s advantages: adherence to modern standards, compatibility with contemporary software, and stronger security.

To plan an effective transition to DNS, Microsoft recommends that organizations audit dependencies, modernize or retire legacy applications that rely on WINS, avoid temporary workarounds, and adopt scalable DNS solutions going forward.

Once WINS is removed from Windows Server, the following components will no longer be available:

• The WINS server role and associated binaries
• The WINS Microsoft Management Console snap-in
• The WINS automation APIs and related management interfaces
