Welcome to the HP Forums 🙂
I would like to take a moment and thank you for using this forum, it is a great place to find answers.
As I understand you want to delete the old wifi network you no longer use,
No worries, as I'll be glad to help you, that said, I'll need a few more details to dissect your concern & provide an accurate solution:
What steps have you taken to delete or forget the old network?
Please let me know if you've already done the below steps so that I could suggest other ways 😉
To simplest way to delete a wireless network profile in Windows 10:
- Click the Network icon in the lower right corner of your screen.

- Click Network Settings.
- Click Manage Wi-Fi settings.

- Under Manage known networks, click the network you want to delete.

- Click Forget. The wireless network profile is deleted.

Let me know how that pans out
I hope you have a good day ahead,
And Feel free to ask any other queries as well,
Considering, this forum has some of the best people in the world available and ready to help.
