Vistaheads Tip#19 - Enable the Hidden "Aurora" Boot Screen in Vista
The default Vista Boot Screen shows a bar with green lines going from left to right. Very spectacular indeed.
There is a "hidden" boot screen that is called Aurora that can be unhidden by:
1. Click on Start, then in the search box key in "msconfig".
2. When MSCONFIG starts click on the Boot tab.
3. Tick the "No GUI boot" checkbox.
4. Click OK and reboot your PC.
