My system password iforget.how I will open?

When we install windows, “Administrator” account will automatically create. So if you forgot your user account password then do this:

Start computer. And when the login screen appears, press Ctrl + atl + Del keys twice and it will display a classic login box. Now type “Administrator” in the user name field and leave password field blank. Then press enter and you should be able to do logging in windows. Now you can reset your user account password from “Control Panel”. You can also do the same thing using Safe Mode.
