My computer is about 7 months old. It is a Sony-Vaio laptop running on Windows Vista Home Premium, with all the latest Windows Update packs - except for Service Pack 1. I was notified only today via Windows Update that I could download it - I wasn't notified earlier. Anyway, I am not at all sure whether I should install SP1. I have read nightmarish stories about SP1 crippling computers so that they couldn't be booted, or that they functioned worse than before. Am I better off without SP1? And why did Windows Update notify me only now? I thought Service Pack 1 had been released in April 2008...? Also, the publishing the date of the service pack is indicated as 9th September 2008 on Windows Update. *confused look*
