If you look at the past, there has never been such an event without trouble. That's not new and all it means is we backup what we can't lose.
Why bother with 8.1 today? We have Classic Shell and the only advantage of being out front are arrows in your back?
I bought a new Dell laptop earlier in the year with Windows 8. I didn't like Windows 8 at that time and re-installed my copy of Windows 7 Pro I had. Now I am trying Windows 8.1 Preview and have decided that when the Update comes out in October that I may want to go to Windows 8.1. My question is: Will I be able to update the Windows 8.1 Preview to Windows 8.1 Pro without any trouble? I want to keep Windows 7 running on another partition but have Windows 8.1 on another in a dual boot situation. If I re-formatted and overwrote Win 8 with Win 7 will I have to buy a new product key to activate it since the product key was embedded in the BIOS of Win 8?
