Windows 10: account security problem

I have a problem that has come back to haunt me. I had a computer and recently sold it. I did a factory reset, but when I set it up again I have to log into my microsoft account and so forth. I changed passwords and so forth, but for some reason what I do on one computer seems to effect ALL my computers. I have several, 3 personal computers and a laptop. if I save a photo on one computer it somehow saves the same photo in all of them. Its a terrible idea for me anyway, as I like to keep my computers seperate. I sold this computer to a hispanic person, and everything went fine until later tha

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:

 

Account problem

Aslam,

Yes, the procedure is complex but I split it into individual steps that, I believe, can be followed by anybody.

Booting into Safe mode is explained in section 3. All steps are included. If there is a step you cannot do then please tell me the para number and which aspect of it is confusing you.

Getting into the built-in Administrator account is explained in section 4. All steps are included. If there is a step you cannot do then please tell me the para number and which aspect of it is confusing you.

Any local account and any MSAccount can be made a "Standard" account or an Admin account. You need to be logged in to an Admin account in order to raise a Standard account to Admin status.
- Once you are logged in to one of the Admin accounts that I suggest that you create, you can go to Settings, Accounts, Family & other users so that you can select the account you want to raise then click on the Change account type button that appears.
- Be wary of promoting then relying upon the current problem account because its user profile might be damaged. I cannot say that it is definitely damaged but only that something has gone wrong.

Microsoft account security code - WHY?

Thanks for the reply Greg.

"If you turn on two-step verification, you’ll get a security code to your email, phone, or authenticator app every time you sign in on
a device that isn't trusted. When two-step verification is turned off, you will only have to verify your identity with security codes periodically, when
there might be a risk to your account security."

Overkill.

As Two-Step verification has never been turned on, I presume MS thinks every time I log into access pages on https://account.microsoft.com/ pages I'm a risk to my account. Even from computers listed in the 'Devices" tab of those pages. Even though I have
to supply my MS password to get to those pages.

Are you suggesting I turn two-step verification on, which is what I don't need?
