Windows 7: How to make your menu bar larger?

Well.. couldn't think of a better title. I'll just try to make it up in the post instead.
So.. I've got a laptop with 1080p screen. And well.. by default, the screen text and everything on the taskbar are very small. So when I installed my Windows, I right away started looking where I could make everything a bit bigger. And I managed to get a result, that satisfied me.
But now, a few hours ago, I started messing around with themes. Thought that I'd browse some themes and so on. But.. then I accidentaly overwrited my current theme (which had all the "zoom settings"), and now I've got a problem. Thing is that while I'm surfing the web (with any browser), the menu bar, the address bar, the tab bar, the bookmark toolbar, they're all so small now - I mean the text is so small, and the tab size is much smaller, etc.
I'm wondering if the themes are backed up somewhere so I could restore it? Or.. maybe system restore might help? Thought I'd ask you, before making any moves.

Go here: Control Panel\Appearance and Personalization\Display and set the display to 125% or 150%

I had 125% on my previous theme (which had everything correctly) and I've got 125% now. And 150% is too large. But I'm just wondering if System Restore might actually help? Gotta back up the files then, I guess.

The screen resolution is stored with the theme. So if you change themes, you may change the screen resolution if that theme has another setting.

A system restore may get you back to the theme with the right resolution (but that's a rather odd way to go about it). User files are not affected by a system restore - only by an image restore.

Window Color and Appearance - Change

Jep, that's probably the place where I changed something after installing Windows, but I have no idea, what I changed. But, I'll try to test with different settings.
