FreeOCR uses Windows Installer to setup up scanning and OCR software on your computer. Its OCR engine is based on the Tesseract engine that is maintained by Google. It recognizes most image types as well as PDFs.

Installing FreeOCR is fairly straightforward. Just double click on the downloaded file and follow the prompts. Depending on your version of Windows, however, you may not find a new program cluster in your start menu for Free OCR. If you can't find it, you can browse to it through "Computer" as shown in the image below.

Just double click on "FreeOCR.exe" and you're on your way. The process is simple (unless the software doesn't recognize your scanner). Just click the "Scan" button, select your scanner, wait for your document to scan and then click the "OCR" button.
In a test scan, Free OCR worked fairly well, although it did not preserve any of the formatting of the scanned document as shown below.
