Note New security updates to Microsoft Vista and NI-DAQ 8.6 or later create random INF files for NI hardware. Windows assigns random file numbers to all INF files, which causes the user to search through several INF files until the correct file is located. If you want to revert back, save a copy of this file as OEMx_original.inf in a different location. 2. Edit the device INF file by opening OEMx.inf with a text editor. At the bottom of this file are the descriptors where Windows looks to
