"Failed to uninstall the device. The device may be required to boot up the computer"


After what seemed to be a successful migration of a dozen or so virtual machines running on an old  VMware ESX 3 host to a shiny new VMware vSphere 5.1 host (via VMware vCenter Converter), I started to see the following error popping up when configuring the new network adapter.
Failed to uninstall the device. The device may be required to boot up the computer
After a little snooping around on the VMware KB site, I found a way to resolve the issue:

Open a command prompt

  1. Type: set devmgr_show_nonpresent_devices=1 and press Enter
  1. Type: devmgmt.msc to open Device Manager and press Enter
Once device manager is up, go to View, Show Hidden Devices. From there you can remove (or disable) the old network adapters. Once that has been done, reboot the machine and you should be good to go!
