Windows Vista only: System tweaking application WinBubble is one of those gems with a killer feature you wouldn't expect—you can add items to context menus and customise certain system icons. WinBubble is very similar to most tweaking applications—including previously mentioned Ultimate Windows Tweaker—but the best features can be found on the Icons and Miscellaneous tabs, where you can customise certain system icons and add your own custom menu entries to the system context menus. Ever wanted to quickly add a new tool to the desktop context menu? No problem! This feature alone makes this no-installation-required software a great addition to your flash drive toolkit, and worth a look for anybody looking to customise their desktop. WinBubble is a free download for Windows Vista. Thanks, austin316gb!
