I presume you are looking for software that converts an image of text to usable text, known as OCR (Optical character recognition).
Did your scanner have a CD with some support programs on it. Many scanners come with 'Lite' versions of OCR software that allow you to convert the scanned image to text that you can use in your wordprocessor. This is the first place to look, as Windows 2K didn't have an OCR program as far as I can remember.
The ability of OCR software to convert images to text obviously depends on the quality of the original image, but it also depends on scanner settings. Follow the software recommended settings. Higher scanning resolutions in my experience have not improved the recognition rate. Grayscale seems better than Black and White, and 200 to 300 dpi usually works OK.
There are other much more sophisticated OCR programs available that let you convert multiple pages at one go, and will retain page layout, and will retain tables as tables, and even convert tables of data to an Excel file. These programs contain dictionaries to help check the conversion and have 'learning' functions to improve text recognition as you correct conversion errors, especially on poor quality images, e.g. scans of photocopied pages.
OmniPage from Nuance is one of these programs - but its not cheap.
If you have access to Windows XP or later:
Windows XP comes with a basic OCR function in its scanning software:
"C:\Program Files\Common Files\Microsoft Shared\MODI\11.0\MSPSCAN.EXE"
which allows you to select a scanner and set some scanner options and scan a page.
After scanning, it opens a window showing the scanned image.
Either select part of the image with the text you want, and Click Copy, or just Copy for the whole document.
The default Copy function attempts to OCR the text and you can paste the resulting text into Word for example.
