I was just trying to trace the ACPI events on Windows when I found this thr= ead while browsing the Mailing list in the train.

My device has multiple of these open app keys (Support, Favorite App, Virtu= al Background, Sound Profile, Dark Mode Toggle), I just wrote a short WMI driv= er to get them working. Have you figured out how to get these working for yourself? I presume the open application key you were talking about is the "star with an S inside", which is also present on my device. --=20 You may reply to this email to add a comment.
