Welcome to the HP Support Forums! It is a great place to find the help you need, both from other users, HP experts and other support personnel.
I understand that you are looking for driver information for your notebook with the Windows 10 upgrade when it becomes available. I am happy to help you with this.
As to what happens with any particular App, no one can really say as the Tech Preview, is still evolving. Until it is in its final form there is no way to answer you. Drivers are a similar issue. HP can only test based on what it currently has, and that is changing. As we get closer to the official release date, information should become clearer. Please visit www.hp.com/go/windows10upgrade for more details. HP will provide information on which units have been tested and qualified with Windows 10 as it becomes available.
