I bought this Acer Aspire laptop new in 2009. It came with Windows 7 Home Premium. I have exhausted all possibilities of installing Service Pack 1. I've tried directly downloading it through Windows Update several times and I just finished unsuccessfully installing it by downloading, burning a dvd and then running that dvd using NTI Media Maker 8 as suggested at the Microsoft Download Center. I've run the diagnostic tools as well, prior to trying to install it. Nothing works. Between downloading, installing, failing to configure, and reverting changes, we're looking at three hours per attempt before I can use it again. The problem is that in order for me to access a secure network so I can do my job, I must have Service Pack 1 installed. Also, I can't install a version of Internet Explorer higher than version 7 unless SP 1 is installed. Hence the question: If I re-buy and reinstall Windows 7, will it come with SP 1 already installed? I've given up trying to install it by itself and will spend the money to re-buy something I already have if necessary. Thanks.
