Windows 10: Windows 10 User Accounts

How do I delete an old User Account I created to a new User Account. In doing so, will I loose my applications and data stored in my laptop? I plan to backup all my data before removing the old User Account and I don't mind reinstalling applications as well but hope I can remain existing. Below are the steps that I have navigated but I dare not do the last step in case it goes wrong. From the last step, if I proceed, will my new account take over since it is already set as Administrator and login to the laptop in future would be using this new account? Would hope for a good advice on this matter.



Below is what I see from Settings which is the old User Account :



Next, I go to Control Panel and I go User Account and select Remove User Account and I see below to Manage Accounts :


Then I select "ABC_Old Account" and I see the below and select "Delete the Account" :


Next I see this asking to delete "ABC_Old Account" and associate files.

Strange Windows 10 User Account issue.

Unfortunately I had done those steps numerous reboots, it just, reappears for no good reason. The base account isn't even a Microsoft account, it's a local account.

I haven't quite tried the built in administrator account on W10, but so far in my experience on my own computer, the built in account seemed to have absolutely no more control than I did on my own.

It's just strange, I go in, it warns me twice about deleting the account, then it's gone. Reboot, and it's back?

EDIT: Just to specify, both command line and Netplwiz both say only HIS account exists on the computer, it doesn't list this rogue account. This is what I meant in my first post about the fact that even Windows doesn't seem to believe it exists, HALF the time. *Frown

 

Strange Windows 10 User Account issue.

Look at this thread,How to Delete a User Account in Windows 10, it may help. You can try the various methods.
Make sure you are using an administrative account when removing the account or log on using the Administrator's account.

Or, if you are patient and know what you are doing, manually remove it.

Either way, Goodluck.

 

Windows 10 Tweaks

As you may already know, Windows 10 (as well as Windows 8) allow you to log in with a valid Microsoft account, instead of creating a local account that only works on your machine. However, you may prefer to keep a local account for privacy reasons. If you do, though, some Windows 10 features—like Cortana—may not work. Despite the default behavior, the Windows 10 Store is not one of them. You can still log in to your Microsoft account for just the Store without switching to a full Microsoft account. The process, however, is not terribly obvious. To do so, follow these steps:

• Launch the Store from your Start menu.
• Click the user icon next to the search box.
• Click “Sign-in” from the menu that appears.
• Choose “Microsoft account” and log in like normal.
• When the “Make it yours” box appears do not enter your password. Instead, click “Sign in to just this app instead.”
