You are in over your head here.
There is no Windows 2003.
There never has been any OS or program called Windows 2003.
You do not have Windows 2003 on your computer.
Microsoft does not make a product named Windows 2003.
You cannot have a product called Windows 2003, because no such thing exists.
If you are getting a pop-up asking for an activation key, it is for
Microsoft Office 2003.
The Microsoft Office that shipped with your computer was a trial version.
The trial period has expired.
Word will no longer work. Word is part of Microsoft Office, and your trial
version has expired.
Microsoft Word is not and never has been part of Windows XP.
You must purchase *MICROSOFT OFFICE* in order to continue to open Word
files.
Your windows XP is fine.
Your *TRIAL* version of Microsoft *OFFICE* has expired, and is now asking
for a code
to continue using it.
I hope this is getting through. If you do not understand the difference
between Windows XP and Microsoft Office, then there is nothing I, or anyone
else, can do.
You *DO NOT* need a code for Windows XP.
Your Windows XP is fine.
Your Microsoft OFFICE 2003 has expired. Word is a part of Microsoft Office.
Word is not included in Windows XP. You cannot enter the 25 digit key for
Windows XP to activate Microsoft Office. Microsoft Office and Windows XP
are completely different, independent programs.
I am running out of ways to try to get you to understand that you are
confused.
You must buy *MICROSOFT OFFICE 2003* if you wish to continue using it.
your *MICROSOFT WINDOWS* is okay.
