What is oem software?
The only practical difference between an OEM copy and a standard copy is that the OEM copy doesn’t come with support. But if you’re savvy enough to know what an OEM copy of application is, you’re probably not going to call Software Vendor for tech support. You’ll probably find solutions to your problems online.
But if you install an OEM copy on say, your parents’ or friend’s computer, then they can’t call Vendor for support. Still, if they trust you to build a machine or update their OS / Software, you’re probably going to be the first person they call in the case of a problem anyway.
