Remember! dont apply dem yet, just keep them in a folder or startup (home site).
choose the version of the country you live in. if you live outside it works aswell (I live outside the countries and i chose England)
Now enter windows safe mode by restarting your pc.
In the lockscreen you should press on SHIFT and restart, this will ttansfer you to a ble option screen. Now press on (troubleshoot -> Advanced options -> more -> startup settings)
Press restar and go to "4" safe mode by pressing f4.
be sure you dont have network connection
Now when you are in the safe windows mode run Guru3d DDU (the dowload file is hidden inside the file so search for somethin i guess say "display driver uninstaller"
in the right cornes choose (GPU)
Then press where it says "unistall and restart".
when you come back to normal windows you can now "activate" the new nvidia driver that was mentioned in the beginning.
When you are finishing the install, remeber to choose "advanced option" in the installation options.
put a cross in the box that says it will set all nvidia drivers to normal and remove all older drivers and profiles.
Now finish the installation and Nvidia controll panell should be located in right click on home.
