This isn't specific to education, and I'm sure that if you need to know things like this, you'll automatically be registered to our update and security blogs, but for the network managers out there, here's a quick note:
Windows Update will automatically deploy Internet Explorer 7 next month, if you are using Windows Server Update Services (WSUS). If you don't want it to, then read more here.
If you're not a network manager, or you are using Windows Vista, or you don't know what WSUS is, then ignore this - it isn't going to affect you...
Although this is the kind of generic technical stuff I try to leave off this blog, because I'd rather be talking about education, I am aware that sometimes holidays\play havoc with your information timescales. This update will come out in half-term for most schools, and I know that's when a lot of staff in education take holidays, so you may need to get things sorted before then.
