Question: Is it a 32 bit or 64 bit operating system?
Document: It was also a pleasure buying through Amazon as opposed to Dell who always turn the whole purchase process into a drawn out pain in the a$$. Fast set up, no glitches, and  I'm amazed at just how little space the unit takes up. I was already familiar with Windows 7 from using it at work, so operating the new system is easy.What more can I say?Good deal all around.
The computer box had been opened and resealed; I was initially very worried as it was advertised as new, but the system seemed OK after setup. However, I will not buy here again.
Please don't take offense, just take advantage of the positive changes in operating systems. Still have Wind 7 on my Laptop but prefer using Win 8.1 on Desktop. However my HP Chromebook beats all for simplicity in web browsing.
thANK YOU
poor rating because no instructions worth a grain of salt as to how to set up. ,  Do we a need an outsider to come in at maybe the cost of the device itself? Ir has been two weeks and I still haven't gotten the printer to work ( don't even ask about the pop up ads scam artists that go after you.telling you about the "divers" that needs to be set up. Drivers, what are drivers?.
i got a good computer.
We wanted a new computer and didn't want Windows 8 (or 8.x for that matter). This model is mid-sized:  The front panel is fairly compact, but the machine is deeper than really small models.The factory packaging was fine, and setup was easy, except that it wanted to operate in U.K. English.
Too small. Customers didn't like this form factor. I won't order this model in the future. Too bad they're priced nicely.
This was purchased for my brother, I was able to research this replacement for him and get it shipped directly to him, he received it all in good order and was able to be up and running quickly.
This computer was delivered promptly and was easy to set up and operate. I recommend both this computer and the vendor who sold it. It does all I want, which is just word processing, surfing and running a few odd programs.
