Acer computers come with a trial version of Windows even though it does not say so on the box or in the documentation. 6 months after using your Acer.. Windows will notify you that it does not pass validation. Acer will not provide you with a product key, nor send you a Windows disk.They will tell you to go buy Windows even though you are still under warranty. Acer has been hit with multiple class action suit's and i would expect this to be one of them very soon. I also had hard drive failure and still have overheating issues. Between being sued and poor products, I wouldn't expect Acer to stay in business much longer.
