Finding drivers for a discontinued laptop.

Toshiba Satellite P55W-C5316
PSPVTU-008001

I just downgraded to Windows 7 and need the touchpad and wifi adatper for my laptop. I came to find the laptop is discontinued and Toshiba doesn't have any drivers on their website anymore.
When entering my model number at https://support.toshiba.com/drivers it list 7 drivers, none of which I need.
I've done some searching around but I can't find a good solution to this. I can find the drivers on Softpedia and other 3rd party sites, but installing drivers from 3rd party sites is a pretty big security risk isn't it? What am I supposed todo here? I find it hard to believe Toshiba wouldn't at least archive the latest versions of the drivers for public download.

 

Do you know what is your WiFi model? If not, use the excellent freeware HWInfo and you can find out. Same for the touchpad. Then you can download it from 3rd party sites

 

@glijo Thanks for your reply. I installed the software which detected my wifi adapter and brought me here to where I installed a similar tool from intel that downloaded and installed the drivers directly from their website. Woo! No more USB wifi adapter!
The touchpad on the other hand I'm not having much luck with. Unless it's hidden I don't think HWInfo picked it up. Intels software didn't pick it up either but I don't think it has anything todo with intel. If anyone has any pointers for me on the touchpad please let me know.

 

1. It's strange you HAVE to install the touchpad drivers. Usually they do work basically out of the box
2. Why Windows 7 and not 10?
3. I see there are touchpad drivers for Windows 10 - try them (or upgrade to windows 10!)
4. Is your bios updated? could help generally
