my machine has Xp home with service pack two installed, the problem is that every time I start my machine it try,s to install photo Gallery, on start up. I do not have the program in any shape or form (I do not need it as I already have a good photo editing software) so I cannot install the program and then remove it useing normal means, i have read some ware that this should be done through the registry but I am not sure how to go about it .
