this file is part of creative labs sound blaster. here is how you remove it, while still in windows mode. what you do first is click start, then run, then type msconfig, click OK, got it? good, then go to startup. Scroll down until you find devldr 16 then disable it by unchecking it, make sure you click apply then Ok. Alright now it's no longer in use by windows. now click my computer, then C: drive, then the windows folder, now system folder. Look for devldr 16. Now highlight it, then click the right sided mouse button, click cut, then click the right mouse button again, go to send to. then send it to your A: drive. the reason it's better to do this is if you need this file for any reason you can allways get back. Better safe than sorry.
