New PowerToys update fixes memory leaks and other issues

Version 0.100.2 landed with emergency fixes for Command Palette Dock and its memory leakage.

Another bug-fixing update is available for PowerToys version 0.100. After releasing version 0.100.1 with a bunch of bug fixes and patches, Microsoft pushed version 0.100.2 to address two important issues with one of Command Palette Dock's features. With PowerToys 0.100.2, Microsoft fixed the performance meter displaying incorrect values and memory leaks, which are particularly unwanted things in the current situation with overpriced PC hardware.

Here is the changelog:

• Reverted a Performance Monitor dock refresh change that forced item refreshes on every metric update
• Fixed a memory leak in the Performance Monitor dock extension by reusing stable network upload/download band items instead of creating new list items on each refresh

For those unfamiliar, Command Palette Dock is a relatively new addition to PowerToys. It is a taskbar-like tool that you can keep on top of the screen to pin various useful widgets, commands, and more. It can display time, weather, your PC's performance metrics, and more. Microsoft introduced the Command Palette Dock in March 2026 in PowerToys 0.98. Microsoft has dedicated documentation for Command Palette Dock, and you can check it out on the official Microsoft Learn website.

You can update PowerToys to the latest version by going to Settings > General and clicking "Check for updates." Alternatively, you can download the installer from GitHub using this link.

In other news, Microsoft is working on a new window-management utility for PowerToys. Called Alt Window Cycle, it will let you use the Alt + ` shortcut to switch between different windows in a single app. You can learn more about the tool here.
