Solved! All steam games crashing at launch

Nov 22, 2018
I have recently been lucky to be given my gfs old laptop which is still significantly better than mine. As soon as Ive got it a went and splurged on some new games from steam but have since discovered none will launch. Not even the most basic games my laptop could run.

When I launch games I get various error messages
- failed to create a graphics device
- cannot run as your video card doesnt support shaders
- Or just 'Launcher stopped working'

The laptop has two video cards and I am sure I have set it to the more advanced Nvidia 850m. Upon reading online advice I have tried updating it from their website but it says the version of windows doesnt support it. Checked windows updates and it said 'No important updates available'

Im at a loss at where to go from here, would anybody be able to help?

get a legit version of windows.
