Windows 7 - Getting an alternate GPU(vga) driver on windows 7...

Ok I know if u have a AMD or NViDiA GPU in your computer it is adviced to install software from either manufacturer on the pc in question and keep it upto date by installing a newer one when they are released...but>>>

In the past while operating on win 7 i managed to mildly do a default display adapter update to a newer proper gpu match one like we used to do back in the days of win98, were one whould simply open a .inf file and that would do the trick. {in my case i used a preinstalled NViDiA driver package and just deleted all the files not really needed until it would install without all the so called nonsence attaced to a simple driver file or files, and that did the trick...seems like they noticed this tweak and have now made it impossible to achive this same result now.

Does any body here know such a method too getting an alternate GPU(vga)
display driver on windows 7...?... since the default Windows 7 ones` just doesn't cut it any more and seems to be out of date ( windows is older than what my Gpu card is) besides the obvious above metioned recomended packages.

If there is a simple way to just help windows let us update it without getting the same effect like the recommended dowloadable packages from either manufacturer with
all the big downloads and resource chewing not~really~useable controlpanels and extra settings tabs and such... it would be better for sure , if not then letz just keep on using what works right.

if u can provide knowledge in achieving this please post it here
