I have some problems with Windows Update and some other Microsoft services. One day, I bought NFS shift for PC and installed it and discovered that the Games for Windows Live client couldn’t connect to the server. Also, when I tried to register a Games for Windows Live account (from play), you must open a page in Internet Explorer, but all I saw when IE opened a "Page Not Found" error. For the reason that, I checked a number of things on my PC and I found that Windows Update were not able to retrieve updates, but the odd thing is that I was able to install updates before do not acquaint with how long before though. I searched that the opening of space for somebody (from inside Windows Live Messenger and IE) is not functioning properly. The same story with Office Outlook Web Access: IE returns a "Page Not Found" error when Firefox displays the logon screen. Because the only clue I have is the error code from Windows Update, it seemed that Microsoft Knowledge Base and tried the solutions exist. All suggestions are welcome.
