Hello my name is Robert and I also own the Toshiba satalite laptop. I am an independent advisor not affiliated with Microsoft or Toshiba.
Laptops are inherently finicky about drivers. Most of their components while made by major manufacturers are custom to that model laptop. The only reliable ways to get drivers are either through the windows update system, or directly through Toshiba as the previous advisor suggested. If neither of those options have drivers then they most likely do not exist yet.
Do not be discouraged though as Toshiba is generally quick to adapt the new drivers so check back with their website often.
Robert independent advisor and customer.
