my computer has,until 2 days ago,always been a single account set up with admin rights.At start up my desktop would appear with no request to logon to my account. since installing Net framework 1.1 (in order to run Nasa's World Wind 1.3 click here ) I am now being shown the logon screen with just my account on it. Net framework has installed itself as a machine account. Does anyone know of a way to enable auto logon so that my desktop appears as it did before? World Wind is pretty impressive by the way but you need broadband and a fast computer >1.5GHz.
