Running Windows XP. Installed an Adobe update last night but I'm not sure if this has anything to do with my problem. When I powered up this morning half my icons were gone, my desktop pic is different and my settings are all different. I tried system restore to 3 different points over the last couple of weeks and it was not able to restore my system. I just started manually fixing everything. I then powered down and restarted. Everything I had just reentered was gone again. Any ideas?
