I'm guessing you didn't make those. If so, you can contact Acer for restore media. I can't tell you how much but last time about 35 bucks. Much cheaper than a trip to the repair shop or a copy of Windows 7.
Sometime around the first of 2012 I purchased a new new Acer laptop computer. About a month later C-net published the the new Windows 8 arrival and had a download for Priview review of the Software. Not realizing the problems it may cause, I downloaded the windowns 8 Preview Review 8400 from your web site. It is the worst experence I have ever had., All the apps are spread all over the front page. It is difficult to find anything to operate the system, Plus I have not found a way to get it off my computer and get back the windows 7 that came with my computer. I have conbsulted tv repairman without any success. I aqm unable to use the computer now and it was only a few months old. I reallize that I should have had better sennce than to down load something I knew nothing about. Now the computer is useless. Can anyone give me any instruction on how to get the computer back to its normal settings when purchased. The computer is no longer of any use to me and I had to purchase another Lap top with windows 7 installed. If you can help I would appreciate any information and help you can provide.
Thank You and I enjoy your site up until this happened.
PLEASE HELP ME..
