For some unknown reason every now and then my windows starts up as if its the first time its been used. All settings have been reset, my email accounts aren't set, it asks if i want a tour etc. All installed programs are still there and thankfully system restore has all the checkpoints in order for me to do a system restore to correct the problem. Does anybody have any idea as to why this happens - I use my pc everyday and this has happened about 6 times in as many months. I cant think of anything that triggers this??
