(1) You don't seem to use the Downloads folder. I guess your way is OK.
(2) I don't like that bugcheck. Do you get a lot of them? Those are blue screen errors. There are many threads on bugchecks that are really sad to look at. They end up checking various hardware components one after the other, swapping RAM chips, installing fans & blowing out dust bunnies. But it could just be software as well.
(3) OS Build 17763.557 was 25 quality updates ago. That's pretty far back...!...

Not sure what to suggest. Need to hit the sack.
