Has anyone ever experienced this? Does anyone know a workaround? My setup depends on manual IP settings. No matter what information I stick in the configuration box, it absolutely will not save the IP settings. At first I thought I was having the phantom NIC problem, where the specific IP address cannot be assigned because it is already 'in use' on a NIC I can no longer see, so I tried other IP addresses. No problem, I'll just change them back, right? I just upgraded my motherboard and CPU, and even though I keep the on board NIC's disabled, and use a PCIe NIC, it didn't recognize them as being the same NIC's after the switch so it reset them to DHCP. In previous versions of Windows 10 I still had the old good control panel, not this new settings nonsense, and in that I could set manual IP addresses. The issue of Windows 10 Settings not working is reported by many users and it always occurs because of corrupted system files, corrupted user account files, an update bug, etc. Computer Configuration > Windows Settings > Security Settings > Local Policies > Security Options > 'Network access: Do not allow storage of passwords and credentials for network authentication' If this policy is enabled, or in-fact was enabled at any point, you won't be able to save credentials no matter what you do. So, I've had my network adapters configured the way I like them for several versions of Windows now.
