Question: Can  you change the os to Windows 7?  I would buy this system if you can.  Thanks.
Document: It's a great computer for a good price. With the windows 8 update it will be excellent. I would buy it again
I fell for the reviews. Fast. responsive, good memory. I bought it for my office computer, expecting like the other reviewers said, I could change it to Windows 7. Except you cannot really. Windows 8 is built into the board. So I decided I would use it for downloads only. Which was working well until it started telling me that I do not have enough memory. Evidently this is an ACER problem. A 8gb ram and terabyte of memory but it stops when you have anything going.
It shipped with no problem and boots up quick. It runs just as well as I expected it to.Also, Windows 8 is not as bad as everyone is making it out to be. If you miss the old 7/Vista system, you can download the Desktop 8 app and it'll be just like your 7.
The computer seems solid and the performance is good. I wish the computer manufacturers including Acer start providing more flexibility when it comes to the operating system...  for examples, I was looking for a good PC without OS at all [or with Windows 7]  but could not find one at Amazon... This PC is good but I gave it 3 stars only because of their bad choice of OS.
I have another computer with Windows 8 and I just operate it on the optional Acer desktop setup which is like Windows 7. This computer had a low price but now I'm reminded that it's probably because not many people like Windows 8 so it's sort of an off-white elephant.
Not running games or any other apps with high video requirements.I do not disagree with other who prefer Windows 7 over Windows 8, but I feel the OS is a separate matter. If one really desires, I suppose the HD could be re-formatted and install Windows 7.
I've used a lap top my entire life so this is my first desktop. What a difference ! It's speedy and holds a lot of memory. I had no issues with set up and its running like a charm. It took a few days to get use to Windows 8 (coming from XP & 7) but 8 is better.... excel is the worst where they changed stuff around but word is the same from what I can tell.
This computer may be OK but Acer made a very big mistake putting Windows 8 on it instead of Windows 7. Trying to do anything useful  with Windows 8 is almost impossible.. I can not say enough bad about Windows 8. I blame Acer for selling a computer with it installed and not warning buyers ahead of time. I plan to put it in the shop and have Windows 8 taken off and Windows 7 put on it.Shame on you Acer.
Windows 8 boot time seems fast. It takes about 54 seconds from the time I turn it on, to the the time the desktop appears with my icons. I like the speed of the wireless card connection to my Verizon hot spot. I like the 45 degree USB/audio jack/mic jack/card reader on the top and up front.With the Intel I5, 1TB HD, and 8 GB RAM fir a reasonable price ($490), I'll give it 5 stars. Thanks Amazon and Acer!
i am beyond unhappy and amazon, who was the actual seller, is going to suffer in sales and reputation for this terrible product they sold me and won't allow or help me return. Acer is also garbage. i would sooner pay triple for a Mac then deal with this again. the Acer chat person made me give him my windows password so that they can log into my computer when i send it to them.
Answer: You definitely can but you'll need your own copy of windows 7. If you're worried about the start bar missing in windows 8, you can always download a mod to add it back in.  I believe Microsoft is also deciding to release an official version as well.
