Question: I would buy it if you could install Windows 7 Professional?
Document: Windows 8 is not. I am certainly computer literate if not savvy. Windows 8 is a hybrid reminiscent of Millennium and Vista. It would be fine if I had a week to just sit here and hack my way into 8LAND but I don't. I have been able to get some patches which have helped but honestly: I really get frustrated when my computer thinks it knows what I want and I am writing a dissertation and no -- it has no clue what I am doing. It would be so great if I could just get an exchange for the same computer with Windows 7 and move on.
I connected the display to my 60 inch HDTV via the HDMI port, bought a  wireless mouse/keyboard and everything works great, good speed, small footprint, easy wireless connection (including my printer and other computers).etc. I am not happy with Windows 8 so I bought Start8 online for $5 which gives you the Windows 7 type Start button and start menu. As for the price, I actually tried to get a better price from Dell directly and could not. Considering tax, shipping etc, the price between Dell and Amazon are only pennies apart.
Don't buy a Dell Product and expect to get support to help you even when it is still under warranty. Their was a problem with mine because of the McCafee Antivirus that was put in my computer at the factory ruined my computer from being able to use Internet Explorer. They could not repair the computer except to say I could no longer use Internet Explore for a search engine, you have to sign in on Bing. I hate using Bing. and this is on a brand new computer that I have had  less than 60 days!!
I had to back up the computer to optical drives (DVD's) and remove the back-up partitions on the hard drive. I would suggest, for future users who want to do this, to select making a Windows 8 back-up rather than a disk image back-up. You only get one shot at it for optical drives. I was able to also make a thumb drive back-up (requires 16 GB flash drive).Why does Windows 8 suck? The intrusive anti-pirating controls are one problem.
You have to enter your email address to boot the computer. Then, since I had bought a Windows computer 5 years ago and had given them my old email address then, they wanted me to verify my address through that email. I had abandoned that email address years ago. I then had to give them my phone number so they could call me. I finally got all this done, then started using the operating system. Microsoft has made the operating system more invisible and harder to modify. This may be safer for regular users, but as somebody who knows my way around operating systems, the barriers to the stuff under the hood are just annoying.
After two weeks of struggling with a computer running on Windows 8 have decided to end these problems and erase all and install more understandable and friendly Windows XP.My friend tell me that this is impossible.Is this true?Grief throw new computer just because it has installed Windows 8
Positives:  Hardware-Fast processor and adequate RAM for the price. I chose a smaller, but faster 7200 rpm hard drive than was available on other computers as speed is more important to me than storage space. The hardware seems great for the price.Negatives:  Software-Windows 8 sucks, and it was harder than usual to be able to set up dual boot with Ubuntu because the computer came with 5 logical partitions on the hard drive. Dell and Microsoft really do not want you to change things easily. These partitions would be invisible to the usual Windows user, but took up a lot of space and added complexity to the Ubuntu Linux installation.
Works great for my media server, runs blu-ray, 3d and anything else I can throw at it. I also love windows 8 (even though it said it came with Windows 7)
Of course the last PC I bought was in 2007, but so far this is super fast and very easy. Loving it! I also appreciate the tip from another buyer on the Start7 software for $5, which makes WIndows 8 look like 7. Very helpful! Overall, so far a great purchase.
I bought another version of this computer for myself a few months ago. It runs perfectly for gaming and internet. I bought this one for my daughter. It runs perfectly for her needs: watching videos and playing games. It has usb ports and a disk drive, the fan isn't noisy.It doesn't come with Office, but there is an app that will take you right to the purchase screen for download if you happen to need Office.As for Windows 8, which is not what is being reviewed, just watch a tutorial before you buy or while you set up your new computer.
Answer: I am not sure if it would accept Windows 7 Professional or not.  I bought Windows 10 and used that.  I just know my old windows documents that were transferred over by the tech for me would not open till I put in the Windows 10.  New computers don't come with Windows already installed anymore.  Not sure why, but I think it should already be in there.  At least a basic version.
