Well it finally arrived – 8 weeks after it was expected. It has now update all my machines and with usual Microsoft efficiency. It took about an hour to an hour and a half dependant on which machine it came down to. If you are running your kit as a standard machine I don’t believe you will see a problem. However, if you have IIS installed it wipes, just as previous Windows versions have, the localhost site content. You will need to reset up any site you were running under localhost, the PHP fastCGI detail and allowed pages like index.php and index.shtml.
