Microsoft has pushed out PowerToys 0.100.0, delivering a leaner installation package and promoting its Command Palette utility to a core component of the suite. Released on June 10, 2026, for Windows 10 and Windows 11, this update shaves over 100 MB from the x64 installer while elevating the once-experimental Command Palette to prime time. Users who have stuck with PowerToys through its evolution will immediately notice the faster, more responsive launcher that now sits at the heart of the toolset.

The installer size reduction alone is a headline grabber. The x64 installer for version 0.99.1 weighed in at roughly 376 MB, but the 0.100.0 release pares that down to about 272 MB. That’s a 27% drop, achieved by stripping out redundant dependencies, compressing resources, and optimizing the packaging pipeline. For anyone on metered connections or systems with tight disk space, this is a meaningful improvement. It also signals a broader effort by the PowerToys team to streamline the entire suite.

But the real story here is Command Palette. First introduced as an experimental module in PowerToys 0.74, Command Palette evolved into a powerful launcher akin to macOS Spotlight or the Windows Run dialog on steroids. With version 0.100.0, it graduates from the “Experimental” tab and becomes a core, always-on utility. The move reflects the community’s adoption and Microsoft’s confidence in the tool. Its default activation shortcut remains Ctrl+Space, summoning a sleek, minimalist text box that can execute commands, open files, manage windows, run scripts, and now even interact with system plugins.

What’s new in Command Palette

Command Palette’s core promotion comes with a raft of enhancements. The launcher’s indexing engine is now faster, with near-instant results for installed apps, settings pages, and recent files. Microsoft has also opened the plugin API to third-party developers, meaning the palette can be extended with everything from clipboard managers to custom workflow automations. A handful of community plugins are already available on the PowerToys GitHub, including a calculator, a currency converter, and a Windows Terminal profile switcher.

The search algorithm now prioritizes exact matches and learns from user behavior over time. Type “pw” and it might suggest PowerToys settings, then lean into that preference the next time you search. The palette also respects Windows’ region and language settings, displaying localized command names and system paths. For power users, a new “Developer Mode” toggle exposes raw command IDs and lets you bind custom shortcuts directly from the palette interface.

Visually, the floating window has been refreshed with Fluent Design touches—rounded corners, subtle shadows, and a blur backdrop that integrates seamlessly with Windows 11’s aesthetic. It supports theming, so if you’re running dark mode, the palette follows suit. The resizable UI now remembers dimensions across sessions, and a compact mode strips away chrome for users who want sheer speed over flair.

Installer size: how they did it

The installer diet wasn’t magic. The engineering team posted a detailed breakdown on the PowerToys repository. The biggest savings came from removing legacy .NET Framework dependencies that were duplicated across modules. Earlier versions of PowerToys bundled separate runtimes for utilities like FancyZones and File Explorer add-ons; now those dependencies are shared and deduplicated during build. The team also switched to a more aggressive compression algorithm for the MSIX deployment, which slashed the final package size without increasing extraction time.

Additionally, several modules received internal refactors that reduced their individual footprints. Image Resizer no longer bundles a full image processing library but leverages Windows’ built-in codecs. Keyboard Manager’s remapping database was optimized, and PowerRename shed a few megabytes by moving to a lighter JSON parser. These changes don’t affect functionality—users will find all the same features intact—but they collectively chopped the installer down to a size that loads faster and updates more quickly via winget or the built-in auto-updater.

Other notable improvements in 0.100.0

Beyond the installer and Command Palette, version 0.100.0 ships with a round of bug fixes and quality-of-life tweaks across the board.

Always On Top

The Always On Top utility now has a configurable border color and thickness. You can set a distinct visual cue for pinned windows, and the border no longer obscures the title bar on maximized applications. A new “click-through” mode lets you interact with windows behind a pinned overlay when holding the Alt key, a feature requested by designers and streamers.

FancyZones

FancyZones, the window-snapping tool that many consider the core of PowerToys, gets a subtle but impactful update. Zone layouts can now be linked to specific monitors, so if you plug in an ultrawide display, PowerToys automatically switches to a pre-configured three-column layout. The editor also supports snapping zones to a virtual grid, making it easier to create perfectly aligned layouts with keyboard shortcuts.

File Explorer add-ons

The preview pane handlers for Markdown, SVG, and source code files have been rewritten for performance. Previewing a 50 MB log file no longer stutters, and syntax highlighting now supports more than 30 languages natively, thanks to an updated TextRenderer engine. PDF preview is also faster, relying on a new lightweight renderer that doesn’t require a full Adobe Acrobat installation.

Mouse utilities

PowerToys’ mouse utilities—Find My Mouse, Mouse Highlighter, and Mouse Jump—now work on multiple monitors with different DPI settings. Find My Mouse adds a new spotlight animation that’s easier to see on bright backgrounds. Mouse Highlighter lets you customize the highlight color and shape, and it plays nicely with high-contrast themes.

Keyboard Manager

The Keyboard Manager now supports remapping shortcuts that include the Fn key on many laptops. This was a long-standing request from users of compact keyboards who wanted to repurpose media keys or the Office key. The remapping UI has also been redesigned to show a live preview of the physical keyboard layout, which significantly cuts down on mapping errors.

Peek

Peek, the file preview tool activated with Ctrl+Space (a shortcut now shared with Command Palette, though they don’t conflict), can now preview webp and heic images. It also supports audio file playback directly in the preview window, complete with a scrubber bar and volume control.

Performance and stability

Every module in PowerToys 0.100.0 benefits from under-the-hood performance tuning. The team integrated a new telemetry opt-in system that respects user privacy while providing anonymized crash reports and usage patterns. This replaces the old system that occasionally spiked CPU usage on startup. Memory management has been improved across the board; on a clean Windows 11 install, PowerToys’ resident processes now consume less than 100 MB of RAM combined, down from about 150 MB in the previous release.

Startup time is also faster. The PowerToys tray icon appears within seconds of login, and background services like FancyZones and Keyboard Manager load asynchronously so they don’t block other startup tasks. If you don’t use a module, it won’t consume resources at all—the lazy-loading mechanism has been extended to cover all utilities, not just those marked experimental.

Community and open-source contributions

PowerToys thrives because of its open-source community, and version 0.100.0 highlights that. More than 50 pull requests from external contributors made it into this release. The list includes minor UI fixes, new translations for the Command Palette, and a handful of plugins that ship as optional installs. Microsoft credited the community by name in the release notes, a gesture that underscores the collaborative nature of the project.

The GitHub repository now includes a comprehensive “Contributing” guide that walks newcomers through setting up a development environment, picking issues labeled “good first issue,” and submitting plugins via the new Plugin Marketplace. The marketplace itself is hosted on GitHub Pages and already contains over 20 verified plugins, ranging from clipboard history search to Azure DevOps integration.

Known issues

No release is without its quirks. The team flagged a handful of known problems that will be addressed in a 0.100.1 patch. On some Windows 10 builds, Command Palette may crash when searching for network paths if the network is slow to respond. A workaround is to disable network indexing in the palette’s settings. Users of ultra-wide monitors have reported that FancyZones occasionally forgets the linked layout after a driver update; resetting the configuration fixes it.

Some antivirus software may still flag the installer as suspicious due to its self-extracting nature. Microsoft continues to work with security vendors to whitelist the binary, but users can verify the download hash via the GitHub releases page. As always, the MSIX package signed with a Microsoft certificate can be installed directly from the Microsoft Store for an extra layer of trust.

How to get PowerToys 0.100.0

You can grab the update through several channels. The easiest is via the built-in auto-updater: just open PowerToys Settings, navigate to the General tab, and click “Check for updates.” You can also download the EXE or MSIX installer from the official GitHub releases page. For command-line aficionados, winget install Microsoft.PowerToys will pull the latest version.

The Microsoft Store version typically trails the GitHub release by a few days due to certification, but the Store now supports side-by-side installation with the standalone version, so you can run both if you want to test the bleeding edge while keeping a stable backup.

The bigger picture

PowerToys has come a long way from its reboot in 2019. What started as a handful of utilities for Windows power users has morphed into an indispensable toolkit with over 15 modules. The shift of Command Palette from experimental to core marks a philosophical change: the suite is no longer just a collection of disjointed tools but a platform for extensibility and workflow automation. With plugins and a growing API, PowerToys is positioned to become the de facto launcher for Windows, something third-party apps like Flow Launcher and Wox have been trying to do for years.

Looking ahead, the roadmap posted on GitHub hints at deeper integration with Windows Copilot and AI-driven suggestions in Command Palette. Whether those materialize in 0.101.0 or further down the line remains to be seen, but the trajectory is clear. For now, version 0.100.0 is a landmark release—smaller, faster, and more cohesive than any before it.
