PowerToys Preview v0.102.2814.0

This is a preview-channel build for the PowerToys 0.102 release train, produced from the stable branch. It follows v0.102.2803.0; the notes below describe changes since that preview, not the complete 0.102 versus 0.101 changelog. This is not the final stable release.

Installer Hashes

Highlights

• Mouse Button Lock: Added opt-in left, right, and middle button locking so dragging and selection can continue without holding a button down.
• Light Switch: Added a CLI for status, theme switching, and schedule control, with JSON output for automation.
• Settings: Added a CLI to inspect module states and save enable/disable changes while PowerToys is closed.
• Command Palette: Fixed dragging packaged apps onto the dock and displaying their loaded icons.
• Quick Accent: Restored the horizontal scrollbar for overflowing character lists.
• Shortcut Guide: Improved startup and indexing, including fixes for rapid-reopen crashes and first-activation flicker.
• Settings: Replaced animated welcome-page GIFs with muted, looping H.264 videos and a fallback image.
• ZoomIt: Fixed DSC configuration to use actual registry-backed settings and notify the running utility of changes.

Command Palette

• Fixed dragging packaged apps onto the dock so pinned entries launch correctly and their icons appear when loaded in #51018 by @jiripolasek

Light Switch

• Added a CLI to query status, set or toggle configured theme targets, and enable or disable schedules on the running Light Switch service, with JSON output for automation in #50459

Mouse Button Lock

• Added opt-in Mouse Button Lock for left, right, and middle buttons so dragging and selection can continue after a long press without continuously holding a button in #49279 by @MuyuanMS and @owenpkent

Quick Accent

• Restored the horizontal scrollbar for overflowing character lists so Quick Accent shows the current position without clipping the scrollbar in #50924 by @daverayment

Settings

• Added a Settings CLI to inspect module states in text or JSON and save enable/disable changes while PowerToys is closed in #50507 by @Copilot and @MuyuanMS
• Replaced animated welcome-page GIFs with muted, looping H.264 videos, with a PowerToys logo fallback when playback is unavailable in #51057 by @Copilot

Shortcut Guide

• Improved startup and shortcut indexing, preventing rapid-reopen crashes and initial overlay flicker while picking up PowerToys shortcut changes on the next launch in #50609 by @daverayment

ZoomIt

• Fixed the ZoomIt DSC resource to read and update actual registry-backed settings, detect configuration drift, and notify a running ZoomIt instance to reload changes in #50551 by @Gijsreyn

Development

• Removed unused central package entries and documented retained dependency pins without changing the versions resolved by existing projects in #50880 by @Copilot
• Moved local build logs into artifacts\logs so context-menu packaging no longer fails when trying to include open MSBuild log files in #51056 by @Copilot
• Removed obsolete analyzer suppressions for retired template code to keep shared build diagnostics easier to maintain in #51061 by @Copilot
• Promoted IL2081 trimming diagnostics to build errors in the shared AOT configuration while retaining explicit project-level exceptions in #51073 by @Copilot
• Aligned main's checked-in release train with stable's existing 0.102 setting; the previous preview already used this release train in #51111 by @Copilot and @LegendaryBlair
• Enabled nullable reference checking across File Explorer preview and thumbnail projects and their unit tests, with annotations and guards that preserve existing preview behavior in #51099 by @Copilot
• Updated PowerToys Run architecture documentation to point contributors to the current plugin-management and query-processing code in #50519 by @ElenaGe216 and @Gavin-Yau
• Enabled warnings-as-errors for the shared UI-test framework after resolving its analyzer warnings and documenting narrowly scoped exceptions in #51085 by @Copilot
• Corrected developer documentation links so readers can reach the referenced Settings, PowerToys Run, and Group Policy files in #51108 by @xThreeh
• Updated Image Resizer observable models for WinRT and AOT compatibility and made the corresponding MVVM generator diagnostic fail the build while preserving settings serialization in #51067 by @Copilot
• Corrected native build configuration warnings, removed an unused COM reference, and separated intermediate output folders without changing shipped filenames or output locations in #51090 by @Copilot

Changes needing final review

Two direct integration commits merged the reviewed main changes into stable without separate PRs: 2646ff0204b8 and 1fca166ef506. Both preserve the existing stable-only PowerDisplay diagnostics omission; no new branch-transition removals were identified.
