I'm not sure I should offer a suggestion, but here goes. If you want to run Windows 7, maybe you could burn a copy of your Windows 8 operating system to a DVD or 2, just so you have your own copy to reinstall at a later time. After you have your own copy of Windows 8 on a couple discs, then maybe you could uninstall it first, and then install Windows 7 if that's what you want to run. Just a suggestion. Not sure if it's a good idea for you but that's what I'd consider. On second thought, maybe you'll need a working operating system to be able to run the PC. I'm thinking Firefox-Mozilla should be in there too. Not sure if you can put 7 in there with the 8 before you remove 8. The Geek Squad boys seem to like Windows 8. They think it's ok. Has a few quirks, but they say it's ok. Personally, I'm using Windows 7 and I am not switching for a while, maybe not till I have to. At least till they find a bunch of bugs during the next year and fix them. I am going to buy the Windows 8 upgrade now. I have a copy set aside for me at Best Buy, with the DVD inside the box. That's so I get the better price now, $70.00 for the Pro version upgrade, before it goes up to $200.00 in February, and have my own hard copy too. But I don't think I'm going to use it for quite awhile.
Of course if you go with 7, you will have to buy it or get another license for one you may have now. And if you go back to 8 later, You'd have to use the one you have now and maybe uninstall the 7. So you want to keep your version of 8 or a new one might cost more than $200.00 later on. The $200.00 price is only to upgrade after January 31 from 7. I haven't installed my own Windows on anything yet so you might want to get another opinion about the feasability of doing this first. I'm just thinking this is how I would do it. More likely I'd have one of the geeks do it to be sure it got done right. I'm thinking it might even be covered by my tech support warranty. I think software installs are covered. Had a crash. They reinstalled 7, for free. Thank God for Carbonite. Thank God for the hardware protection too. New motherboard, hard drive, burner,..... covered.
