I love time-saving tips. I especially love time-saving tips that actually work. Here's one. How to defragment Windows Vista faster than by using the built-in defrag tool.
The never-ending two-step defragmenting process of Vista can soon become a thing of the past. With certain tools, we were able to cut defragmentation time of 25 GBs of files with Vista Ultimate from 82 minutes to 6 minutes!!! That is defragmenting 10X faster than the built-in Vista defragmenter! The tutorial also works with Windows 2000 and XP.

Right now, many things are probably whirling around in your head:
- Is this true? Yes, it is.
- Does it work? Yes. We will show you charts on hard drive fragments before and after defragmentation.
- This has got to cost money. Absolutely free.
Nice one! I've tried this and it's certainly a LOT faster than mucking about with the built-in defrag tool.
