Microsoft fixes PowerToys install errors in new update

A new PowerToys update is now available for download. Microsoft has just released version 0.94.1 to address bugs with the previous update. Unlike version 0.94, which introduced some much-needed changes and upgrades, today's release is made solely to fix a single bug preventing installs from GitHub, winget, and the Microsoft Store.

According to reports on GitHub, installing PowerToys 0.94 sometimes gets stuck with the following bootstrapper error: Failed to load SilentFilesInUseBAFunction.dll (0x8007007e). This behavior was observed when installing PowerToys from any source (GitHub, winget, or the Microsoft Store) with or without elevated privileges. Luckily, Microsoft fixed the problem relatively quickly with version 0.94.1, which is now available for download. Here is its modest changelog:

• Installer: Resolved the installer setup problem, enabling successful installation from GitHub, winget, and Microsoft Store by fixing the “Failed to load SilentFilesInUseBAFunction.dll (0x8007007e)” bootstrapper error.

In case you missed it, PowerToys 0.94 was released earlier this month with a couple of much-needed improvements. The app now has a dedicated search bar, allowing you to quickly find necessary settings and modules. PowerToys now has a shortcut conflict detector in case you have a bunch of actions assigned to a single shortcut, plus a new gliding cursor mode for Mouse Pointer Crosshairs, which offers improved accessibility.

PowerToys 0.94 was not the biggest feature update, but in version 0.95, developers promise to introduce several major changes. For one, look out for a new module that will take care of automatic theme switching in Windows 11 based on your schedule, plus a fully revamped Keyboard Manager user interface.

You can download PowerToys 0.94.1 from GitHub or the Microsoft Store. Additionally, you can run Windows Terminal and type winget install Microsoft.PowerToys -s winget.
