a large aperture setting, sent today by microsoft service. I think it relates to the graphics card. I do not know if it contains improvements to the graphics. Total download is 113.5 MB. I think it is version 2012. Also, HP, suggested that I go to the platform window7. indeed. Vista, provides less stability. windows7 format, contains the HD. and many tools. so. to complete these steps do I leave my computer, or decided not to make the best choice, since it is automated. but I would like the opinion of HP, for this renewal. I turned 50 today aperture setting. microsoft platform, is very regular update on.
