Don't have a product registration key.

System was installed when I bought the computer. Do not know the product key? Have not really used up until the last. Can you help me if you can send it to my address that you do not file.

New computers coming often pre-installed with Windows 7 have what is called a recovery partition. This is used to reinstall an operating system in the case of a system failure. To access it, you need to start when you start your computer by pressing a function key. This can be either F1, F2, F9, F10, F11, F12 key DEL or tab. See the manual that came with your PC for instructions on how to reinstall Windows.

This is how the recovery partition is accessible to most popular brands...

For Dell, press CTRL + F11 directly after switching on the device

For HP, press F11 directly after switching on the device

For LG, press F11 directly after switching on the device

For Toshiba, press and hold "0" BEFORE and during the power upward

For Acer, press and hold ALT + F10, as soon as you see the logo

For Asus, press F9, as soon as you see the Asus logo.

For Samsung, press F4 to the power upward...

For Fujitsu, press the F8 key directly after the power

Advent, restart your computer. Then, press F10 repeatedly until the message "Starting system recovery"

Sony VAIO, reboot and press "F8" or "F10" repeatedly until the screen "Advanced Boot Options".

The product key located on the COA sticker.

You can identify the edition on COA sticker on your machine, at the top/side or bottom compartment or battery (laptop) if it's a desktop computer.
