I am trying to return my tower to factory setting.It keeps asking for a25 character number.


Are you sure you're back to factory settings? That 25 character number sounds like the Certificate of Authentication (COA) key for the Operating System. Look on the side and back of your computer for the COA Sticker. It tells you what Operating System you have and it will have a series of 5 letters and numbers (25 to be exact) that is the key to validate and activate your operating system.

I lost my product key wat is the 25 character product key


Sorry--you are out of luck here. We will not provide software keys to people who want them. If you have an authentic CD with the software on it, you might try contacting Microsoft. I have seen them help before, but they will require the serial number of the actual CD or DVD to prove you have a legitimate copy.

25-character product key of Microsoft office home and student 2007


Just to add to Antioch's comment you will be asked by Microsoft to fax through to them confirmation of purchase, and possibly a certificate of authenticity. They will then issue a further product key.

If it was a version supplied by Compaq, then contact them - presuming you registered your purchase they should be able to trace the record and replace your key.

HELP!


Do you need to reinstall MS Word or was it already installed. If it was, I wonder why you need the number now? If it was already installed there is a free and safe utility that will allow you to read the serial number from your system. Download Belarc from this link http://www.belarc.com/free_download.html

This will check all microsoft sotware on your system and reveal the keys. It will also give you a useful system analysis, for example it will tell you if your microsoft security is fully up to date etc. It is well respected, spyware free software.

Alternatively, if you're using Windows XP, you could use system restore to return your computer to a point where you were previously able to use MS Word, then use Belarc and record the number.

If you have reinstalled the software, or you are using a new computer, I'm afraid that you will need to find your CD case or obtain a new number. Or recover the number from your previous computer. Hope this helps....
