That's a Microsoft Works document.
Four options:
1. Have your OS reinstalled from the system recovery media that came with the PC. That should contain the program, assuming it came with the PC indeed.
2. Use the MS Works CD that came with your PC. All PC's I've seen that came with MS Works came with the installation CD. Yours, of course, might be a difference.
3. Buy MS Works and continue using it.
4. http://filext.com/file-extension/WPS says the free MS Word Viewer 2003 (maybe the current one also) can open it. I don't know from my own experience. Worth a try, however.

Exactly what do I need to open documents with file extension .wps? I recently had my operating system re-installed & now I cannot open them because my Office application (came pre-installed when I bought computer) is not on computer anymore & PC Doctors installed Open Office, which doesn't recognize .wps. I've been looking at Office progams on CNET but the more I read, the more confused I become. At this point I don't care if I have to buy it, but I'd like to keep cost under $100, if possible.
