Vista x64 Ultimate SP1, Geforce 7800 GT In spite of successful installation the Nvidia "181.20_geforce_winvista_64bit_international_whql" driver, shown in the details tab of device manager the driver tab displays always the old version 126.96.36.19969. Should it not show 188.8.131.5220? From where reads windows device manager its information? In the registry I found entries with the old number and replaced it, but device manager continues with the old version number. Any ideas?
