Question: I want to make sure it has windows 7 not windows 8
Document: Did a lot of shopping to find this deal, and still has windows 7 which was a plus. Had one issue with dropping internet connection. I will say that Dell support was excellent, helpful and immediately solved the problem. Even called 24 hours later to make sure that the problem remained solved.
This laptop is thin, powerful and more powerful than I need and it is a great value. I don't need the most powerful 1000, 2000 dollar laptop. Only few do. This one is great. I would not want Windows 8 on anything without a touch screen. Love Windows 7.
It definitely has good features. It's light, attractive, instant on, the price was great, it still operates Windows 7 (a plus for me as I didn't want 8) but . . . it seems to be plagued with &#34;Dell&#34; problems. Dell, unlike some other manufacturers does not send you updates when it is time to download new software (drivers, for example).
I am not sure this is Windows 7 problem or dell issue.I would certainly not recommend this product to anyone.
Great price. I like Windows 7 too. I didn't have to make any wifi setting changes to use with my wireless DSL router which is over a year old. Nice screen. No manuals with it or even at dell.com, except for hardware upgrades or generic laptop versions which appear to be adequate.
From the very beginning started to have problems with the Internet connection. Sometimes it just disappears. It is not my wifi, because other two notebooks I have work perfectly well. Googled it and seems like a common problem on dell notebooks with Windows 7. I also find the touch-pad not very responsive: you have to hit it really hard in order to make a click. I tried to change that in the settings, but could not.
This unit works very well, its is fast and has a built in CD drive which makes very good for handling old programs. I only did 4 stars because it came with Windows 8 instead of 7 as advertised and Win 8 takes some getting used too.
I did tons of research to find a working computer for school work. This computer is not for gaming or heavy operations...however I have ran it on Windows 7 and Windows 8 and it works marvelously. I also have ran visual basic 2012 with high level programming (which causes a lot of lag), and it works great.
I haven't had a problem with the wifi connection like other people have, but I've only had the laptop for 1 week so maybe it's too new. This laptop has Windows 7 which I'm really happy with because I don't really like the new format of Windows 8. Bottom line, I'd recommend this laptop. If you can't decide on the bigger or smaller screen, try and think if you like the idea of being more portable or less portable.
This is a very good laptop. It has a built-in DVD drive, which is a real plus. Not only that but it has Windows 7 instead of Windows 8, which is a pain in the behind.
Answer: I purchased the Dell Inspiron 14z 14-Inch Laptop Core i5-3317U in Jan. 2013.  This computer has the Windows 7 operating system. Initially I had difficulty w/ this computer, it kept losing the WIFI signal.  I eventually got ahold of someone at Dell that knew about this problem.  It was a simple software problem that they were able to fix by downloading a new driver.  My only complaint is that it took several calls before I found someone at Dell who knew about this easy fix.  Besides the WIFI problem, this computer has been great.  It is very light and you get quite a bit for the price.
