Using Same Code Twice on Same Machine

Hello dwe Welcome to the Se7en Forums!

The original product key for any retail upgrade or full version 7 dvd is seen on a small sticker pasted to the insert inside the plastic case the disk(s) come in. That's one item you write down whenever first getting a new Windows disk for any version and keep track of.

The insert itself should still be in the case unless you lost that in which case you are kind of sunk! If the laptop came with 7 preinstalled with the same edition you would use the key on the laptop's own sticker. Look around for the insert there however and write the key down in a safe place besides keeping that with the case.

Where did you get Win7? Do you have the original packaging? There should be an insert with your Product Key. If so, it can be reinstalled as often as you like.

Do you have a windows.old folder in the root drive which was created by the reinstall? If so, you can roll back to the old Win7 to try to repair it or get the product key from the registry: http://support.microsoft.com/default.aspx/kb/971760

dwe already mentioned performing an upgrade install over the original. He simply needs to find the insert with the product key sticker on that and type that in.

To extend the 30days, dwe, you can run Windows upto 120 days by following the guide for extension of the trial period. You still need to find your key however. https://www.sevenforums.com/tutorials...-120-days.html
