Windows 7 - Notification Area

I've searched this and other sites for an answer to the question "how do I increase the size of the notification area icons"? (Earlier called the system tray).
All threads seem to lead to adjustments to the quick launch bar.
I can use the advanced appearance windows but this also affects the scrolling bars which I don't want.
It seems that these icons are fixed at 21x21 pixels.
Is there a way around this?

Is this any good to you?

Right-click Desktop>Personalize>Windows Color>Advance Appearance Settings>Item drop-down list>Active Title Bar>Select Size & Color.

Customize notification area icons.
Not sure if you can change their size though.

Hi Alan

Yes you are right that those icons are of fixed size . But we have noticed that a few themers like Mr Grim, Paulioug and nofx hane changed the size of system elements like Start Menu and notification area clock , which we thought to be of fixed size earlier.

So, there might be a way, which is not generally known . I guess theme designers can describe this situation in a better way .

I just tried to change the size of the sound icon in SndVolSSO.dll the original size was 32 x 32 I changed it to 48 x 48 and it did not make any difference the size stayed the same on taskbar. So I'm going to say they are a fixed size. If you go to Control Panel> Display you can change your display settings and it does change the size of little bit but it makes everything else on your computer larger to.

Thanks to all for the quick replies.
Yes, it looks like I'll have to live with the situation.

That's a shame really as it would be nice to have the option.

Thanks for the update.
