Windows 7 upgrade?

Hi, quite a while ago i bought a windows 7 "upgrade pack" from the microsoft store to upgrade vista and i used the code that was given to me and worked perfectly. i am now wondering if it is possible to use it again? and if so, how many times?

You'll need another license key champ for more installs on other machines simultaneously. Re-installation though on the same machine is unlimited - after 3 or so times just activate via phone.

When it asks for the key, hit continue, then call them up and tell them what your doing. They're usually pretty nice about it.  

ahh, okay... so will they give you a new key or something?

ahh, but if my laptop has completely died will i still need to buy a new key? 

and when you say hit continue do you mean put the used key in? Thank you very much for replying! 

No, They don't give you a new key, they just enable the old one. After the install in setup, you will hit a screen asking for the product key, you don't need to enter it to hit continue, so just do that.
