Where is the 24 hour clock...?
Yep, thats my desktop!
And yes, that is Windows 7 with my own modifications, the only way I ever could use this OS properly!
The modifications/guides I used/followed is
Classic Shell (Program)
7 Taskbar Tweaker (Program)
Quicklaunch guide: Howtogeek.com
Other usefull settings: Run programs like Windows Live Messenger in compatability mode for Windows Vista to make them more compatible with the classic taskbar.
