If you’ll never use it, its not worth keeping. If you will ever use it it is.. master of the obvious I know :D

Seriously that’s about the best answer I can give, it will work fine for any projects you’d need glass and unless its tempered (moderately unlikely in window glass) it should cut fine (tempered glass will crumble when you try to cut it).

If you aren’t going to use it look for a local rebuildit or habitat store to donate it to unstead of throwing it away (or craigslist it if you’re motivated enough).
