I tried to update an old Dell XPS 15" from 2011 with Windows 7 installed.

First I tried to install the updates but I always had network errors like "The updates can't be downloaded"

I try to use the ping command and it worked.

But when I tried to load a web page I had again a network error.

After I tried to boot into safe mode and I managed to load some websites (but this mode prevents to update Windows)

Do you have any suggestions ? Why can't I load web pages ? It's like a port is blocked by a software, I don't know...

Try reinitialising the network states. Run the following commands in an elevated cmd shell:

  • Reset WINSOCK entries to installation defaults:

    netsh winsock reset catalog

  • Reset TCP/IP stack to installation defaults:

    netsh int ip reset reset.log

  • Reset Firewall to installation defaults:

    netsh advfirewall reset

  • Flush DNS resolver cache:

    ipconfig /flushdns

  • Renew DNS client registration and refresh DHCP leases:

    ipconfig /registerdns

  • Flush routing table (reboot required):

    route /f

It seems like some installed product is blocking your access to some websites.

The likeliest product is your security software or anti-virus. Try to disable them and check again.

You may use Safe Mode with Network to update the computer.

You could also power-cycle your router to verify if it is the source of the problem .
