I am running windows 7 build 7229 and before i ran windows update, everything worked fine. Now, when i load windows, the login screen appears, but after logging in, the screen goes black. I have to use alt+ctrl+dlt/task manager and start explorer.exe manually to get the desktop/wallapaper/taskbar/icons to appear. I ran a full virus scan with kaspersky 2010 and no malware was detected. If anyone can help me with this problem it would be much appreciated!
