I have suddenly been unable to access Windows Update. I now get a message saying 'Your organisation has decided to provide updates internally rather than through Windows Update....' and then tells me to contact my network administrator! I am using the same home PC I've used for 5 years now and I've been using Windows Update since Windows 98! Could it have something to do with a recent installation of Xteq Systems system administrator (an excellent alternative to Power Toys)? Whether it is or not how do I fix this?
