If you manage Windows Servers, plan for removal of Windows Internet Name Service (WINS). WINS was officially deprecated since Windows Server 2022 and will be removed from all Windows Server releases following Windows Server 2025. Standard support will continue through the lifecycle of Windows Server 2025, until November 2034. We encourage you to migrate to modern Domain Name System (DNS)-based name resolution solutions before then. When will this happen: WINS deprecation was announced in Windows Server 2022. Deprecation means the feature remains supported and maintained, but there is no further active development or new functionality planned. November 2034 is the end of the lifecycle for Windows Server 2025, which also marks the end of support for WINS. How this will affect your organization: Once removal takes effect, the following components will no longer be part of Windows Server: WI

Microsoft has identified an issue affecting some organizations using hotpatch updates on devices running Windows 11 Enterprise, version 25H2. After installing the hotpatch update KB5068966 released November 11, 2025, affected devices repeatedly download and install the same update when a Windows Update scan is run. This behavior does not impact device functionality; only the update history will reflect the latest installation timestamp. An out-of-band (OOB) update was released today, November 20, 2025, to address this issue. This is a cumulative update, so you do not need to apply any previous updates before installing this update, as it supersedes all previous updates for affected versions. If you have not yet deployed the November 2025 hotpatch update (KB5068966) on Windows 11, version 25H2 devices in your environment, we recommend you apply this OOB update (KB5072753) instead.

Secure Boot helps ensure that only trusted software runs during the boot sequence. It uses cryptographic keys, known as certificate authorities (CAs), to validate that firmware modules come from a trusted source. After 15 years, the Secure Boot certificates that are part of many Windows systems will start expiring in June 2026. These certificates were originally issued in 2011. Many Windows PCs manufactured since 2024 already have updated (2023) certificates. For the remaining devices, we recommend that you start monitoring the progress of certificate updates today as well as prepare for and install new certificates on devices that aren’t automatically getting them through Windows updates. An initial set of tools and guidance is now available to support you in this effort. When will this happen:While Microsoft will deliver the new 2023 Secure Boot certificates through Windows monthly upd
