Every time you go to Microsoft Update, Microsoft’s WGA (Windows Genuine Advantage) program checks whether your copy of Windows XP is pirated. Now, Microsoft has begun quietly distributing a WGA Notifications program to some users via Automatic Updates.

This article appears in the October 06 issue of PC Advisor, which is available now in all good newsagents.

The problem is that the automated process sometimes gets it wrong, repeatedly sending you a pop-up alert claiming that your legitimate Windows copy is bogus.

Users will have the option of not installing the notifier when it pops up a licence agreement for them to accept. At some point it will become mandatory, though. And be aware that once installed, the program can’t be removed.
