Pretty much any game in borderless windowed. A few I have been playing recently are Skyforge, ARK, and SWTOR.

Sorry for the late reply I realized the forums do not notify me of replies by email. it has been this way for about 4 months I believe. Start 10 updates I do not believe it was related to a windows update. I am running Start 10 1.11 and Windows 10 Pro Insider Preview 14393. I had this issue prior to switching to insider preview a few weeks ago so that should not have affected it. Is there any other info I can provide that would be helpful?
If I bring up the start menu over a fullscreen window using the windows key it does not bring the taskbar to the front this is inconsistent with default windows behavior and is not how this functioned in the past. This has been an issue for the last 2 or 3 updates. I am running Windows 10 x64 Pro and Start10 1.11.
