Microsoft has released a new feature update for PowerToys. Version 0.64.0 is now available for download with two brand-new utilities, settings backup, and a massive list of fixes.

PowerToys 0.64.0 introduces a new File Locksmith utility (shown below). It lets you see what process or processes use the selected file or folder, preventing them from deletion or modification. The second new tool provides an easy and convenient UI for editing the Hosts file—no more diving into the system drive and opening Hosts in Notepad.

You can view details about processes and even end them if necessary.

Another noteworthy feature in version 0.64.0 is the ability to back up and restore settings. You can now store your PowerToys settings, custom key bindings, and other parameters in a file. It is a quick and easy way to get your preferences to another device or store them safely. Finally, PowerToys gets Group Policy Objects settings for enabling or disabling utilities on managed devices.

Here is the full changelog for PowerToys 0.64.0:


  • New utility: File Locksmith allows seeing which processes are currently using the selected files.
