Let me preface: Don't think this exact question has been asked/answered. When I tried adding to a related thread, asking for help, my post was deleted within minutes! Not giving me much of a play outside of starting my own question.
Really need help from a Windows Guru! Myself and our IT vendor could not solve it! On 12/10 my Windows toolbar suddenly changed to Classic/XP view, but a restart fixed it. Then on 12/18 or 19 my Alt-Tab changed to "classic" view and I don't like it nor can I revert it back to Aero!
System > Advanced > Performance Settings - "Aero Peek" "Desktop Comp" all still on. Tried Task Bar "preview desktop with Aero Peek" still checked. IT even tried creating the "classic" Alt-Tab entry into the Registry, restart, then deleting, logging off/on and still there. I'm somewhat clueless. Obviously using an "Aero" theme because Aero Peek in toolbar is still working. Looked into color profiles (currently 32bit True Color) Did a driver query today and found 2 strange drivers installed on 12/17. Maybe the culprits? amdkmdag and amdkmdap Anyone have some knowledge on this issue?
