I have laptop with Windows 8.1 (64 bit) running. Now I want to develop an e-commerce website for my new start-up which is very small. Whether I can install Magento CE on my laptop with Windows 8.1 (64 bit). If so, from where I can download the CE version? Otherwise will you recommend to change the OS to Linux on laptop? Please suggest.
I have already done this. you can do following (overall steps)
Download XMAPP for windows 8.1 from below link, install it on your windows as usual https://www.apachefriends.org/download.html
Download Magento CE edition http://www.magentocommerce.com/download
Extract and copy the files to htdocs folder of your xampp instllated directory
Browse the folder in browser and magento installation will start, follow the steps and you are done.
