Please

Hi,

My name is Deepa and I work for the Social Media and Community Team at Dell. In order to reset the password, we need to do a complete operating system reinstallation and you will need recovery CDs for doing that.

In order to help you better please reply with system model number.

Thanks and Regards

Find out if there is any rest button on the base of your laptop if not.
Now when you just switch on your laptop press F2 and enter into the BIOS setup mode from there using the keyboard enter into password setting reset and change password from there.
This way you can get a new windows login password use it for future.
