Forgot password fo nextbook 7p12-8g

If you're willing to reset to factory defaults, then there is a way to fix this. However, the reset will delete all data and any apps installed that didn't come with the Nextbook Tablet originally.

you will have to format the drive and install the windows back on it. Download a windows disk of pirateproxy.se and then use rufus to make a bootable image pop ur stik in a usb port restart the pc select first boot priority the stik not the hard drive you can do so by entering the bios ( pressing f2 or Del after pressing the power button ) and from there u go to boot and change the settings then save and exit and then ur good to go. hope this helped.
