If you find that you're not getting an IP address from the DHCP server you can follow theses steps:
1. Open command prompt as administrator (CTRL + X)
2. Type netsh winsock reset catalog and press enter
3. Type netsh int ipv4 reset reset.log and press enter
4. Restart your PC
If at first you don't succeed; call it version 1.0
Windows 10 update causes network issues - Not getting IP Address
Whenever this is entered, netsh int ipv4 reset reset.log, my PC is telling me that access is denied. It's my home PC and I am the admin, so why is this happening? I know it's probably something simple.
In my experience Windows updates in the best possible situation do nothing with your system, nothing good or bad BUT in all other situation it cause some kind of problem, small or big, ignorable or not-ignorable SO after installing Windows I ALWAYS disable Windows Update Service.
