there's a site http://www.hp.com/country/us/en/mda/windows7/upgra... if you have an hp comp. But the computer had to have been purchased from June 26, 2009 - January 31, 2010. Maybe there's other offers, but thats the only one I know of

No, the update is not for free. Some companies (ASUS) do it for free for some laptops, but the upgrade definitely costs something.

UPDATE: If you bought your complete computer after the 1. of July, you will gat the update for free.

not all people will give you free

but try to ask Microsoft support

or your computer brand Support
