I am using Maxthon for a browser. That is really irrelevant though as opening CCleaner doesn't happen inside of the browser, you can size the window of it however you like. I opened it up and used Photoscape to capture a screenshot.
I prefer to use most programs utilizing the whole screen if possible. The only thing that I find window tiling useful for is working with spreadsheets. I run the taskbar on auto-hide and keep on top of other windows, this makes it really easy to access any of your open programs and still be able to see everything in them. You have to do entirely too much scrolling when using sized windows to see all of the info in them. Just my opinion though, everybody does what works best for them.
I also don't like to keep a lot of shortcuts on my desktop, I put them in my Quick Launch bar instead accessible through the taskbar. I don't like a lot of clutter.
