Hello, my name is Sorbari and I am 14 year old going into highschool. I'm offering to install Microsoft Windows 8.1 Enterprise 64bit on your laptop for only $30, activated I might add. I preform the installation through a flash drive which has the OS on it. As of right now, I'm only doing clean installs which means when I install it all the data on your laptop will be removed with the install. In other words, your laptop will be like one that was bought right out of the store. Once installed, I can setup your computer with any prefered web browser and set it as the default if you would like. I could also easily install other necessary programs like adobe, java, adblock, etc. at your request. If you want Microsoft Office, it would be an extra $20.
