Windows 10: re-registering access key code.

I received a call yesterday saying I must re-register my access key and pay $400 for a life time key ID, this has to be done before the new year, is this true? My knowledge of computer, well to say, non existing, so any help from y'all would be appreciated.

Remove account


I suggest you backup your personalized files first before removing the account.
To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:
   
   Code:

   net user test /del

 

One computer cannot access other network computers.


So I've tried every troubleshooting step I know:

• Double checked that Net Bios was enabled
• Ran a bunch of network commands:
  • flushed DNS
  • registered dns
  • pinged and located the named computers successfully
• Reset my router to factory settings

Nothing works when I try to access via explorer. I'm still baffled by the fact that every other computer can access each other AND access this computer. It's just the outgoing connection from this machine that doesn't work.

Any thoughts?
