I tried RyamVM's update package and it does correct the problem. I looked into my SVCPACK folder after I integrated RyanVM's update pack and noticed several (.cat) catalog files and only one .exe file. The .exe file is for KB951072. After I installed windows I went the add/remove programs in the control panel and checked show hotfixes and the only one that appeared was KB951072. Out of curiousity I chose a couple of update.exe files that I downloaded from MS that are the same as the catalog files that RyanVM's update pack supposedly integrated, to see if I would get a message that said hotfix or update already installed. Didn't get any messages. So that makes me wonder if the .cat files are useless without a matching .exe file as in the case with KB951072. What do you think? The .cat files are only there to satisfy Windows File Protection. I don't know why that .exe is there. With Ryan's pack all files are directly integrated, so that .exe should not come from his pack. Cheers Is that executable tzchange.exe by chance? If so yes, there was one hotfix that redid a bunch of time zone definitions, and tzchange gets run by Ryan at T-13 to fix it all up.
