Windows 10: Lost admin username and password

I seem to have inadvertantly deleted my Admin username and password and am now unable to unable to uninstall any programs, log in to system restore or to re-set my computer. Attempting to do any of these produces the message "you do not have permission to uninstall/use this program." I am using Windows 10, and would be very grateful if anyone could help me resolve this problem. As I'm relatively new to computing, I'd also be grateful if any answer could be kept simple.

admin password?

You can reset the Admin Password using Windows XP repair; See Here for step by step.

lost admin password

Here you go:

1. Create a desktop shortcut for cmd.exe.
2. Right-click it, then left-click Run as administrator.
3. Accept the challenge. You will get a black frame.
4. Type these commands and press Enter after each:
   
   net users
   
   (to see a list of all user accounts)
   
   net user "John Doe" 12345678
   
   (to set John's password to 12345678)

Deleting the "other admin account" would be equivalent to throwing away your spare house key. Why would you want to do this?

 

Forgotten admin password.

Thanks guys. Just confirming that the instructions have worked and all of the account passwords are sorted out. Passwords have been stored securely so they won't be lost again!

One thing I noticed after creating the temp admin account is that you need to change it to a standard account afterwards otherwise it will be the primary admin account.
