They ran Windows Update about a year ago and their display got messed up. They used system restore to back out the update and the display was back to normal. Recently they ran Update again and the display got messed up again (duh!). This time, they weren't able to do a restore.
Something in the update process reset the display configuration settings, including adapter type, to base level defaults. The current adapter type setting is "vga compatible display adapter" with 256 colors on 800*600 desktop area. That explains why the wallpaper picture of her dog is messed up. What I don't know is how to fix it.
Without tearing the computer apart to look at the video card, is there any way to find out what the proper settings should be? This computer is used in a medical office and I really don't want to screw anything up. Can I get it to do a plug & play search to detect the proper device? Is there someplace in the registry I can look where the previous settings might be stored?
