If not to make things simpler for you, then for the sheer delight of it, it's kind of fun to make your Windows PC look like a Mac. A full theme from FlyakiteOSX, sounds and all, makes it a breeze.
Want a Mac look on your Windows machine? Skins and themes would be nice, but there's more to that when you want to REALLY emulate a Mac OSX interface entirely. There are plenty of programs available to emulate specific features of OSX, e.g. Finder, icons, etc [example].
But Flyakite OSX is a project that's looking mature, and it comes with a very complete theme, including sounds and mouse cursors and Explorer customization, things you don't typically expect from a simple 'theme'.
The website goes for a Mac look itself, which is a bit painful, but it's worth the download.
Before you go for it, some caveats
- The performance of your machine in general may be affected, of course. Not too much though.
- The theme does fundamentally change some core files like Explorer.exe but (a) it makes a backup so you can go back with a simple uninstall, and (b) it doesn't screw up any additional functionality like my Groove button on my Explorer bar.
- I don't like shadows under my windows, but that seems to built-in in the skin.
- Some things like Windows Media Player will not change. WMP has its own skin, which remains untouched.
