@RegalBeagle When that happened to me I just sent the PC back so they could properly set it up.
@RegalBeagle Format the PC and install linux. Congrats, you have a new PC.
Ask them if you can access through citrix or virtual desktop - just work around it.
@Zeb I haven't checked to see if they locked the BIOS down. Might make for an after work project with a cold brewksi to assuage my incredulity.
