Windows Feedback app in Windows 10 Technical Preview allows users to send their feedback regarding Windows 10 experience to Microsoft. Using this app, users can browser existing issues, suggestions from users and even add or report their own issues. The search feature inside this app was slow at times and users reported it to Microsoft. Microsoft has now fixed it and the search speed in the feedback app is now much better.
