Unknown devices on my Microsoft account

Hello Flemmingk,

Could these other devices be from friends that you may have signed in to your Microsoft account on for something?

Either way, you can remove these devices.

Afterwards to be safe, I would recommend to change the password of your Microsoft account, and enable two-step verification if you haven't already.

Hi Hitendra,

Thank you for posting in Microsoft Community. I understand your concern and I am glad to assist you.

I would suggest you to switch your Microsoft account to a Local account first and then switch back with a new Microsoft account. Please refer to the following steps:

Step 1:

• Type Manage your accounts
  in the search bar and click on it
• Click on "sign in with a local account instead"
• Press next and complete the process.
• If you do not have a local account, leave the credentials blank and proceed.

Step 2: Now, on the newly converted Local account, follow these steps to add a new MSA.

1. In the Start search, type "Manage your accounts" and press Enter.

2. Choose 'Accounts'.

3. Click on "sign in with a local account instead"

4. Enter the Microsoft account ID and Password and click Next.

Unknown devices on my Microsoft account

Thanks Brink
I get different reactions every time I try to delete a device, but the result is that I cannot remove the devices.
I'll go back to local accounts and delete the Microsoft account.
I changed to Microsoft account because I wanted to use the Continue on PC feature. This feature doesn't work so I think that I'll just forget about it.
Thanks for your interest.
