6th time was the charm! Well, Windows Media Center is working on my Windows 8.1 Pro laptop. Currently scanning the laptops' harddrive for errors to see if that fixes the slow to start/login problem.
Still no word as to whether or not I can get a Windows 8.1 Pro with Media Center ISO/installation disc.
After 6 hours with Microsoft support working on my laptop with little or no success, my problematic computer has been punted up to Tech Tier 2. More things will be tried, but I have sinking feeling that Alan is right, that it would take less time for me to just reinstall windows, and then the rest of the programs.
