Where do you get the message?
The wording is the standard WGA warning that comes with the manual access and choosing custom at windows update site, but that does not mean it is not one of the many actual microsoft messages faked by rogue anti malware gangs.
Do you have automatic updates turned on? Is it a new install or a reinstall on an oem computer with a retail disk?
Microsoft makes changes to the WGA several time a month and each time I update a reinstalled system I have to agree to its install via windows update. It is also required to install Microsoft Security essentials. Microsoft assumes that all of it's user base are pirates until proven innocent over and over again.
