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...

  • Please include in your post the error code mentioned in the error message. The code should have 8 letters and look like "8024402F" or be prefaced by "0x" such as "0x8024402F". – harrymc Aug 21 '17 at 10:16

I always had network errors like "The updates can't be downloaded"

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

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

  • Thanks a lot for your clear answer and sorry for the deadline for response. I executed your commands. Now (without booting in safe mode) I have, sometimes, 200 http code when I load some web page and some time some "timeout error". Moreover when I use the "windows 10 update assistant", the client is not enable to download anything... – Adrien G Aug 23 '17 at 14:02
  • @AdrienG It's working now? – DavidPostill Aug 23 '17 at 21:08
  • From the comment on my answer, it seems that the poster decided to reformat and install Windows 10. So this post has no clear solution. – harrymc Aug 24 '17 at 6:38
  • @harrymc the DavidPostill's answer helped me to browse some websites I couldn't reach before. So we can consider his answer as a solution :) – Adrien G Aug 24 '17 at 10:28
  • This was just an informative note for DavidPostill. – harrymc Aug 24 '17 at 11:02

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 .
