Can any one tell me what this is/means?

I'm referring to the 20k2nd thing.

Your drive icon changed? I'm unable to find anything about a 20k2nd. Did you install anything new recently?

Actually, I think that says 2Dk2nd. Seems to be related to fighting games.

Someone probably changed your C drive icon... assuming you let someone else use it.

Rovencrone is right it is 2Dk2nd.

I agree with Kadushy.
