It goes on to ask me to check my internet connection, but mine is fine. Network troubleshooter says there is a problem because Windows could not detect this network's proxy settings.I have checked internet properties - connections - LAN settings and "automatically detect settings" is the only ticked box. In settings "PROXY" the "automatically detect settings" is on. I have run SFC and DISM scans and all appears O.K. I have restarted the network adapter. I have checked that my network adapter for updated drivers but mine are O.K. I have checked the DNS server and internet protocol settings are correct. Another online suggestion was to "flush DNS and reset TCP/IP" - didn't correct the problem. I also reset Windows sockets and IP - no improvement. Finally I decided to use my well trusted Macrium Reflect backup and to roll back the C Drive to before my last successful Windows update which was on 25th January. This should have cured the problem [Macrium has never failed me in the past] and I was disappointed and amazed to find that the problem had not gone away. I even tried reverting my system to last December but without solving the problem. I cannot see why if my system was receiving windows updates normally back then why it does not still do so after reversion. Help would be appreciated.
