What do those errors say?
Look into Event Viewer (Start|Administrative Tools|Event Viewer). Click on "System" in the left panel. Do you see RedBall error icon(s) timestamped at the exact time the problem occurred?   If so, click on the RedBall. The first message will have some data on what the problem is, but usually it is not too easy to understand. Click the blue link.  On the next window click the link to send a report to Microsoft.    Another window should open (though it may take some time for the information in the right panel to appear) which may offer some more understandable info and maybe even a solution.

Specific to Windows Update--Open Windows Update|click on Review your Update History" in the left panel.  Some reasons for the failure and good info often can be found.
Error  0x80004015 often is a firewall problem
