Whenever I install the Realtek audio driver then afterwards Windows 7-x64 reports that the winsxs.dll has a corrupt checksum! I have tried this several times and with drivers from both the Asus and Intel homepage. It's always the Realtek driver that causes this corruption after a clean Windows installation.
Even if I reinstall the winsxs.dll from a Linux boot disk it doesn't help. I believe this means it is a root kit that causes the corruption?
