Since upgrading to Windows 10, the log-on screen comes up quickly, but after logging on, the desktop takes more than 2 minutes to appear. During this delay, the screen is black with nothing else appearing.
At first I thought it was the Spy Hunter program because Task Manager showed it using a significant amount of resources during that time. But I uninstalled Spy Hunter and the delay is exactly the same. Task Manager does not show any large use of resources now.
What could be causing this delay?
