I would like to reinstall with the same cd window7.

I would like to install window7 professional again after some of the files were damaged.

I have known what is the product key and installed product IDS previously, but I do not know where one CD I used cause I have a lot of CD

in society and that some lose the license stickers.

Microsoft Office 2007 also have the same problem.

How can I solve this problem?

The computer will have a sticker on the case of machinery which has a SNID on it

You can use this snid to search the site of the factory for the version 32 or 64 bit that came on it

This is the dvd that you want to use.

In case of doubt use the 64-bit first.

The key to activate one or the other.

The office is another story windows don't comes with pre-installed office who has been manufacturing that it packed in the installation

Who I could contact them and see how to use restore the system to factory State, so your desktop is like when you first on the machine after having received it.
