Microsoft has released PowerToys 0.19 in a huge bug fix that aims to increase performance and stability in the tools. Microsoft did not release any new tools or features but instead focused on fixing over 100 issues to improve stability and performance. The bulk of the issues fixed were in the PowerToy Run app, which can now correctly detect Steam games, hidden files, and Terminal. In this release, it will be the last time during upgrade you’ll see Windows Explorer flash on you.
