Lost or forgot Windows 10 laptop password and have no password reset disk? Following three methods would show how you can do to reset Windows 10 laptop password without disk and with no damage to your laptop.
Even though you don't have Windows 10 password reset disk created before laptop is locked, you still could effectively reset Windows 10 laptop forgotten or lost password if you have enabled default administrator, Windows password recovery tool or Windows 10 installation CD.
Windows 10 built-in administrator is disabled by default. So when we need to use it, it should have been enabled with command and another admin account while laptop is accessible or you could enable built-in administrator when locked out.
net user administrator /active:yes
Then with enabled built-in administrator, everyone could easily reset Windows 10 laptop lost password.
On Windows 10 logon screen, when you see built-in Administrator appears at the left bottom side like other local user accounts. Just select it and click Sign in button to login Windows 10 without password if you have not set.
After successfully accessing Windows 10 laptop with default administrator, go to Settings> Account > Other users, and you can see all users that you can reset password for.
2-1 Press Win + X, choose Command Prompt (Admin) and click Yes to run Command Prompt.
2-2 Reset Windows 10 laptop local user forgotten password with command "net user <username> <password>".
Eg. If you want to reset password for Windows 10 user "isunshare", you can type command "net user isunshare abc" and press Enter in Command Prompt.
Instantly, Command Prompt would response with message "The command completed successfully". It means that user "isunshare" password has been reset to "abc". Besides password reset, you could also do anything on Windows 10 laptop with privileges of default administrator, such as creating password reset disk, changing Windows system settings etc.
Note: So powerful default administrator it is. But generally, in order to protect Windows 10 laptop from unwilling attack, it is not recommended to keep built-in administrator enable all the time. Therefore, probably built-in administrator is disabled when your Windows 10 laptop password forgot, and if you want to reset forgotten password to unlock Windows 10 laptop, you would need to find another way.

But you should know this method is a little difficult than above ones. If you are not ready, please think about and learn how it works at first. Otherwise, some operation error would lead to Windows system broke.
Step 1: Boot locked laptop from Windows 10 installation DVD. Make sure that your laptop setup is configured to boot from a DVD and that UEFI and Secure Boot are disabled.
Step 2: Press Shift + F10 to open a command prompt on locked laptop.
Step 3: Replace the file utilman.exe with cmd.exe. Before you do this, you should make a copy of utilman.exe so that you can restore it after Windows 10 laptop password reset. Note that you can only restore this file if you boot again from the Windows 10 DVD. (D:\ is system disk)
Command that you can copy utilman.exe and replace utilman.exe with cmd.exe:
move d:\windows\system32\utilman.exe d:\
copy d:\windows\system32\cmd.exe d:\windows\system32\utilman.exe
Step 4: Remove the DVD and restart your problematic Windows 10 installation.
Step 5: On Windows 10 sign-in page, click Utility Manager icon at the bottom.
Since we have replaced the utilman.exe with cmd.exe, Command Prompt would open now instead of Utility Manager. Don’t care about pop-up error message.
Step 6: Reset Windows 10 local account lost password with following command.
net user <username> <password>
After password change completely, you have to boot from Windows 10 setup DVD again and follow step 1-2 to restore utilman.exe with command prompt.
