How put password to my router to protekt my net.

If you lost windows password, you can go into safe mode (F8 when booting up) to recover windows password while you forgot user account password, but if you forgot administrator password, there is no way to change it, you must use software to recover administrator password. Last week, I forgot my Windows administrator password. Finally I use Windows Password Reset 9.0 to recover my Windows password successfully

If you want to reset windows password, there are many third party tools can help you if you have lost windows password. Just download and install it, you can remove and reset windows password instantly. I recommend you use this: http://www.passwordseeker.com
