On Tuesday Sept 16, my desktop running Windows Vista Home Premium had an update waiting to install ( Windows update SP1 ). So I went ahead and ran the update install. All went well until the final portion. I got a message saying update failed reverting system back to pre-install state (I'm paraphrasing here ) Anyway, it restored my system and everything is running correctly, EXCEPT ( you knew there'd be and EXCEPT coming ) now it keeps telling me I have updates ready to install. ( the same one that failed ) My question is: I would like to delete this update and try to download it again. ( the download may have been corrupt ) Will doing a system restore to the day before the update download enable me to actually download the update again?
