Lost Windows Key

Hi Saravanan,

I would suggest you to follow the steps below and check if it helps.

To start Product Activation:

• Go to Start, then select Settings, choose
  Update & security, and then select Activation.
• If your device is not activated, the Activate by phone option will be available.

Hope this information is helpful.

A Product ID does not help.

There is no public list of Product Keys available.

And we have no product keys to give you.

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

If you have lost it, you have to buy another Windows 7 package if you want to stay with 7, which Microsoft no longer sells.

If OEM preinstalled (Dell, HP, etc.) license:

The COA sticker, which has the Product Key on it, is either on the underside of the Laptop or in the Battery Compartment.

With a Desktop it is either on the side, rear or top of the Computer Case.



Product Key finder programs do NOT find a useable product key on OEM preinstalled operating systems (Dell, HP, etc.)

Key Finder Programs used on preinstalled Operating Systems only find the Manufacturer's Product Key which was used on multiple machines
