Windows 11 users who installed the September renewal of 2025 may have initially thought that it was a minor update. The update, known as KB5065426, appeared to be a typical patch from Microsoft. However, upon closer inspection, the changes included in this update turned out to be more significant than initially perceived.
The update quietly removes two outdated tools from the system that were still present for some users. These tools are PowerShell 2.0 and the Windows Management Instrument-Line (WMIC) console. These tools, once popular among administrators and advanced users, are now considered outdated and unsafe by Microsoft.
PowerShell 2.0, which allowed administrators to work with a separate Windows command shell, had become a potential source of vulnerabilities in recent years. Microsoft has now eliminated this outdated tool, leaving the newer PowerShell version 7.5 in the system. WMIC, on the other hand, was used by corporate clients to collect data about computers on the network, but it has also become obsolete. Microsoft states that these tools are rarely used and pose unnecessary risks.
In addition to removing the outdated components, the update also prepares computers for the upcoming release of Windows 11 25H2, expected to launch in October. Users interested in trying out a preview version of this update can do so now.
Microsoft has also announced plans to provide administrators with more control over the system’s composition in the future. This will include the ability to disable built-in applications and certain AI functions using group policies, making Windows 11 lighter and less burdened with unnecessary services.
