HP has made several configurations of Stream computers so it is hard to be definitive in regard to exactly what yours has. However, minimum system requirements for installing and running WordPerfect 2021 are surprisingly light. So long as you have about 3 GB free space on your hard drive and 2 GB RAM you should be able to run it with any of the processors that HP has used in the Stream computers. I am also assuming that you are still running Windows, of course. It isn't going to run like a rocket, particularly when your computer needs to access the hard drive, but it will run and be acceptable, similar to other things you run now. The only other approach would be to run Web-based apps like MS Office 365... but if I were you I'd stick with WordPerfect even just in order to use "Reveal Codes," a feature that makes life so much easier!
