More info needed--model computer, operating system and why you had to use sys restore. The Windows 10 password is your Microsoft Account password you setup when you installed windows 10 or setup a new computer with 10.
Hi LARRY LYNN,
What is the exact system model? What is the current OS installed on the system?
If you are referring to a local acct on the system, then enable the built in admin account and reset the password - http://bit.ly/1JoFhcw
If it s a Microsoft account, then reset the password here - https://account.live.com/password/reset

Also, please click my DELL-username and write me a private conversation with the service tag and your contact details(Name and Email) for case records.
Let us know if you have any other queries.
