Windows 7 and Windows 8 automatically look for outdated Device Drivers, and updates them as needed, using ONLY Windows Update. There's absolutely no need to go looking for Device Drivers manually. And just so you know, it's your PC manufacturer that gives the latest version of each Device Driver to Microsoft.
And, this has nothing to do with version number R2.71 that you refer to, unless the Device Driver Manufacturer says it runs on your specific PC, by Make and Model Number.
Click on the following link, my friend, to get to the downloads page for the Realtek High Definition Audio Codecs. Do note that there are two separate drivers, one for 32-bit Windows and one for 64-bit Windows.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
