Windows 7: How do you change the color of the square around a selected icon?

I want to change the color of the square that surrounds your icon when clicked, i want mine to be orange so it fits in with the rest of my theme. anyone know of a way to do it at all?

Are You talking about this??

yes exactly, is that a special program or something? and is it only for the border? or can you change the fill color and transparency too?

You need program that can edit aero.msstyle
I used restorator
then extract from aero.msstyle images with No. 6xx.png (see pic.)
edit and import new edited images and save (not save as) aero.msstyle
On desktop selection I used only 2px border all is transparent.

is there a possibility that you could layout a file path for me? im not too good with customization and stuff, i downloaded restorator. i just need to know how to get to aero.msstyle

and what should i use to edit images? just like photoshop or is there something built into restorator?

U can use photoshop or paint.net (more compatible with msstyles)
Then follow instructions in pic.1
Pic2. instructions to replace Aero.msstyles with modified one
(assuming that before a classic theme is selected not basic or aero)
Ps. U must take ownership of that file first search the forum for instruction

do you think there is a problem if my aero.msstyle file is named aero?

i put in an attachment for the picture, but this step. i cant find the drop menu that lets me choose what type of files i can view

If its size it's about 1mb + - is the right one
Mine is 1.6mb but heavy modified
I have disabled in folder options
"hide extensions for known file types"
when this option enabled
in my win say
Programs
AllFiles

all of this has been so helpful and the only thing i am having trouble with is trying to import those edited png files back into the aero.msstyle folder. i have all the pngs and i might edit them a little more but i cant find out how to import them through restorator. do i have to go through a different process?
