I saw this issue randomly on Windows PCs due to IPV6 TCP checksum
Try the following on the problem Windows machine:
- Open the Device Manager -> Network Adapters -> Network Interface
(Ethernet NIC):- Under the Network Adapter -> Advanced Tab, disable these options
if present:TCP Checksum Offloading (IPV6) -> Disabled
UDP Checksum Offloading (IPV6) -> Disabled
- Try Windows update again
