Ok so a few days ago i set a system restore to Dec. 31, but after i did it and stuff i realized that on Dec 31 i updated my windows media player (i have no idea if that has anything to with a system restore or not, if it doesn't please stop me now) so now my windows media player doesn't open at all when i try to open it, it just makes the little hourglass and then the cursor goes back to normal and nothing happens. so i want to undo the system restore but when i try to open the system restore window up again it does the same thing as when i try to open windows media player, only when i click on it twice it comes up but its a blank screen (i went to the store and came back and it was still blank), so idk if there is some sort of relation here, but i just want to know how to reverse it.

Try going to Microsoft's site and update your Windows Media Player again.

tried that already, i even brought my windows media player down to 10 and updated it to 11, but i got nothing

well, i had a trojan that made World of Warcraft not able to run (i don't know the specifics). I scanned my computer with 4 different virus scanners and windows defender and couldn't find it, so my friend told me to try to system restore it.

Try uninstalling then reinstalling WMP

wmp doesn't let you, it only lets you down-grade to the next lowest version of wmp (like 10-9 and 9-8)

Yeah, you can uninstall it.

Go to add/remove progams.
On the left side click add/remove windows components.
Scroll to the bottom of the list and you'll see WMP, just uncheck it and hit next.

Do the same thing and recheck the box to reinstall.

I would restart after the uninstall.

well i tried to uninstall it and even restarted after uninstalling it but when i reinstall it i still get nothing.

Alright i ran hijackthis and here are my results:
