Microsoft PowerToys v0.101.2453.0 Preview Adds Keyboard Manager Search, Command Palette Virtualization
The latest preview tackles performance and usability at scale across four main utilities.
Microsoft dropped a new preview build of PowerToys and it is clearly targeting users who actually stretch the project past its default settings. Version 0.101.2453.0 lands with search and bulk deletion for Keyboard Manager, virtualized grid views for Command Palette, smarter folder counts in Peek, and a spatial audio fix for ZoomIt.
Keyboard Manager finally gets a search bar
The headline change lands in Keyboard Manager. If you have ever mapped out more than a dozen key remaps and watched the flat list stretch into a scrolling nightmare, this pull request closes a seven-year-old issue. You get real-time case-insensitive search across key names, target paths, and app filters. Modifier toggles let you isolate Win, Ctrl, Alt, or Shift combinations. Multi-select mode rounds out the feature with confirmation-bulk deletion so hidden rows do not accidentally get wiped.
The editor-only implementation means the actual remap engine and config schema stay untouched. WinUI's ICollectionView handles the filtering overhead. Community contributor @MasaYan24 shipped 938 lines of additions to make it happen. The feature validates cleanly against a roughly eighty-entry test configuration.
Command Palette and Peek get performance overhauls
Command Palette's grid view went through a similar surgery. Microsoft engineer @jiripolasek swapped the custom WrapPanel for WinUI's native ItemsWrapGrid, which finally enables container virtualization. Only the items in your current viewport get realized now. Keyboard navigation got an upgrade too. Arrow keys, page up, page down, and section headers wrap cleanly across partial rows. The PR also quietly patched a teardown crash when navigating back out of the view.
Peek is keeping pace. Folder previews now display live file and subfolder counts alongside a scan spinner. A warning icon replaces the old generic error state when enumeration stumbles on inaccessible paths. Memory allocation dropped from 128 MB down to 47 MB by switching from DirectoryInfo to FileSystemEnumerable. That is a 63 percent cut in allocations.
The ZoomIt fix sounds minor until you are actually trying to record a screen demo with spatial audio enabled. On machines reporting more than two channels, Media Foundation would try to encode an 8-channel HE-AAC track. The AAC decoder chokes at 5.1 channels and you are left with a silent video. The patch forces a stereo fallback when the channel count exceeds two. Mark Russinovich personally shipped the fix, which tracks.
A scatter of smaller fixes round out the release. Crop And Lock now plays nicer with display scaling. FancyZones stops treating Shift as permanently held after an RDP session. Mouse Without Borders correctly inherits the logged-on user permissions for received files. Command Palette handles Store-only extension detection better, and the Clock dock band finally supports ISO week-date formatting.
Behind the scenes, the team added twenty-two end-to-end UI tests for Quick Accent, cleared up shutdown races in the test runner, and re-enabled the AI issue triage pipeline after aligning compiler versions. It is a steady stream of work. Milestone 46 for v0.102 is already tracking thirty-eight open issues ahead of the October 5 due date.
