AskWoody and other sources are reporting that Microsoft released a W-10 graphics driver for Sandy Bridge and Ivy Bridge, 126.96.36.19959. The Microsoft link, Microsoft Update Catalog, offers no explanation as to supported chipsets (or anything else, for that matter). Did 188.8.131.5259 come from Intel? If not, how can Microsoft give it a number in the Intel style?
I cannot confirm if the driver mentioned is from our site since we do not have control over Microsoft releasing drivers. The styling inquiry you are referring to should be addressed by Microsoft since we do not have any information in regard to that specific driver style.
