How do I remove the system tray?

[vman51]

Well, long story short, I want to remove the battery icon in my system tray. I'm unsure how it got there, whether it be a program I added or if its stock.

These are the programs that are installed (I already searched for options in all of these):
HTC Home
HTC Audio Manager
HTC Home Customizer
Card Export II
Resco registry
Resco file explorer
Google Maps
Pocket Wake Up
LVM Time

I tried to look up some registry tweaks for it, but I the one I found didnt do anything:
[HKEY_LOCAL_MACHINE\Services\Power]
"ShowIcon"=dword:00000000

Any advice?
