Windows 10: How do I remove a device?

Hi there, I have a laptop powered by windows 10 . It's not brand new,it's a used one. Sometimes when I try to login to some website using my gmail account it says my device isn't recognised and Google wants to verify that its me. So when I click the verify button it has given instructions. It says to take my Oneplus 3T edvice and go to settings and do what it tells.But actually we don't have a Oneplus 3T device. Actually I don't have any device connected to my laptop. As I said this laptop of mine is used so somehow still maybe the previous owner's device is connected and that might be a problem.ANYONE KNOWS A WAY TO DISCONNECT THE PREVIOUS OWNER'S DEVICE?

Please someone help me quick.
Waiting for someone to respond,
Best Regards,
Thank You

How can I remove this virus remnant?

I was also going to suggest Autoruns.

Check to make sure it isn't attaching itself to explorer. It should be the 3rd thing listed in Autoruns, the listing for the Shell. It should just be Explorer.exe. If it is anything else, that might be your problem.

Hi,

I suggest you to log into account.microsoft.com and check whether the account is listed there.

I also suggest you to follow the steps below to remove the account and check if it helps.

• Press Windows +R to open run command.
• Type netplwiz.
• In the dialogue box that appears. Select the account that you wish to remove.
