We received a computer with viruses and the subsequent fix caused a problem with Windows after the login. So then we did a Windows repair and so now this computer is in an activation loop. Microsoft used to do free technical support on this particular issue, but now they don't. Do computer shops have a standard attack scheme for this? The details are once I enter the password a message appears that asks if I want to activate. Once I choose yes, I see the background with no icons or taskbar and a functional mouse cursor. Ctl-alt-del does nothing. I have worked this same issue with Microsoft support in the past with no success. They have you remove the oobetimer and change other registry settings and files, but they never fix the issue. Have other shops had any success with this issue?
