Administrator password forgot,UAC problem

So,i had windows 7 and i had an admin account there with a password that i forgot.I've installed windows 10 and my administrator account was working but a few weeks ago i've logged in with local account cause with administrator didn't let me to install spotify,so i was thinking to log in with local account option,so i did it,when i wanted to run a program there was UAC and asked me to put my old windows 7 account password.
Now i lost my admin privileges and I don't know my password,i can't acces anything.And there says that the account that is named "Sprite" is in another account x-pc/ASPNET (I don't want to say that "x" name).Please help me with this problem if you understood what my problem is.

When UAC asks you to provide the password for an admin account it offers you the first account it finds, in this case the old W7 one. Click on the 'more choices' link near the bottom left of the UAC prompt. This offers you a choice of all the admin accounts available (you may need to scroll down to find the one you want).

This is how UAC looks like... i don't see more choices or somethig
Oh,and i forgot to say,my old account that with w7 doens't even exist right now,i mean when i press to sign out and sign in with that account doesn't happen anything.

Then UAC can find no other admin accounts for you to use. You may need to enable the built-in Administrator account (no password by default), then you can log on as Administrator.

See Option Four here:

Enable or Disable Built-in Administrator in Command Prompt at Boot
NOTE: This option is good for when you are unable to sign in to Windows 10.

You can then create a new local admin account or reset the password for existing accounts. The built-in Administrator account cannot by default run Modern Windows Apps. This includes the Settings app, so use WinKey + R and run:

control userpasswords2

Remember to disable the built-in Administrator after you have finished using it. By then you should be able to use Option One.

That's why I said try Option Four, where it says to...

1. Boot from your Windows 10 installation USB or recovery drive...

If you don't have a Recovery Drive you can't make one as a standard user, UAC will stop you. You should be able to make an installation USB with Microsoft's Media Creation Tool.

Note
Leaving the Use the recommended options for this PC box checked will have the Media Creation Tool create a USB flash drive that's the same language, edition, and architecture as the current PC.

As I understand it you do not have a recovery drive or install USB to boot from, and UAC is stopping you from making one. There is another way to boot to the command prompt. Press and hold the power button to force an abrupt shutdown, then turn the PC back on. Do this three times, at the third boot up the PC will boot saying 'preparing recovery environment'. Take the Advanced options (do NOT reset this PC) and you will get to the command prompt. Then you should be able to follow the Option Four instructions from step 2 onwards.

2. In the command prompt, type regedit, and press Enter. (see screenshot below step 3)

I see it's past midnight in your timezone. Best to print out Option Four and sleep on it, you can tackle this tomorrow when you are feeling more refreshed.

I tried it but it's showing a list with administrator accounts,there is just that account that i don't know the password.It's asking again for password.

If you kill the power three times, on the third boot a Windows 10 PC will boot to the recovery environment, showing this screen.


Choose Advanced Options to get to this...


Click on Troubleshoot takes you here...


Click on Advanced Options to get this...


Where you should click on Command Prompt. The command prompt will open, now you can carry on from step 2 in Option Four of @Brink's Tutorial I linked to earlier. At no point should you be asked for an account or password.

If this is not what happens for you please describe what you do see, with screenshots if possible.
