I had trouble reinstalling Microsoft Office 2011. Microsoft tech support scanned the computer for malware or other problems and tried to sell me a one week 24/7 tech support service for $149 or a 1 year policy for $199. This would make the computer "just like new." I have experienced this kind of sales pitch before and have NO patience for it. I had already done a scan of the computer and told the technician I was taking the laptop to the Mac store, which I did and switched to "Pages." I like Microsoft Word better, but, from my experience, Microsoft support cannot touch Apple support.
