Customizing Windows power-user utilities historically required jumping through command-line hoops or digging through third-party repositories. Microsoft is streamlining that process for desktop enthusiasts. The company released PowerToys version 0.100.0 on June 10, 2026, introducing a dedicated Extension Gallery directly into the Command Palette.
The update brings a centralized storefront experience to the utility suite. Users can now browse, discover, update, and remove community-made extensions right from the Command Palette Settings. The tool completely eliminates the friction of manually managing add-ons, letting users handle discovering and installing custom tools natively.
Microsoft built the gallery as a curated front-end rather than a physical file host. The interface is powered by the official microsoft/CmdPal-Extensions repository on GitHub. When a user clicks to add a new tool, the gallery actively links them to the underlying installation sources, routing the downloads through WinGet or the Microsoft Store.
Under the hood, this update marks a core architectural shift for the entire software suite. PowerToys is now running entirely on the .NET 10 framework. The upgrade significantly reduced the x64 installer footprint from roughly 376MB down to 272MB while boosting application performance.
How Microsoft is Standardizing Developer Submissions
The introduction of the built-in gallery triggers a strict policy shift for third-party developers building custom Command Palette actions. To have their extensions surface natively in the new settings menu, creators must now adhere to rigid metadata formatting rules.
Developers are required to submit their additions directly to the CmdPal-Extensions repository via pull requests for Microsoft’s approval. This creates a standardized quality control checkpoint for the Windows ecosystem, ensuring all listed plugins point to secure, verified WinGet or Store links without restricting the open-source nature of the tools themselves.
