Hello, I have this Toshiba L855D-S5117 Laptop reformatted to Windows 7 (64-Bit) unfortunately after browsing through Toshiba website and sorting it with the model for wireless and graphics drivers, I have found none. This is the website with my model's drivers for Windows 7 (64-Bit) https://support.toshiba.com/support/modelHome?freeText=3621615&osId=31 . Prior to this (before reformatting) the laptop has it Windows 8 installed, I gave this to my brother and now he wanted me to reformat this to Windows 7. But now, I have trouble finding with appropriate drivers. Should I stick with Windows 8? Thank you.
