Advanced System Tweaker is a Windows tweaking tool with a couple of unusual extras.

At first glance the program doesn't look too impressive. It only comes with 37 Windows tweaks, for instance, covering the usual areas: memory optimisations, interface tweaks, networking improvements, Explorer speedups and so on.

And an inflexible interface means they're not too well presented. Most tweak descriptions are too long to view in their pane, for instance. You can't resize this or maximise the window, either, so have to scroll horizontally to read them.

But there are good points, too. Choose an option like "Memory Tweaks", say, and the program will explain that it can speed up your PC by telling Windows to keep more items in memory. Sounds good, but if you're an expert Windows user you'll still want more information.

And you can get it, too, just by clicking the Detailed Information bar, which (amongst other data) shows you exactly which Registry settings the tweak will apply. It's the same for every tweak here: the program is completely transparent about what it's doing.

But that's not all. Advanced System Tweaker also supports "Add Ons", which means you can extend its abilities by downloading more tweaks online (well, eventually, there's only one available as we write), or creating new ones of your own. So in just a few minutes you can extend the program with many of your own favourite Windows tweaks, which could make it far more useful.

Build 2.0.0 is a major new release with these changes:

- Major program change. In the previous versions you could only run 1 tweak at a time. Now you can select the tweaks you want first and then apply them all at once.
- Multiple code changes and some minor bug fixes.
- Added frame containers and lines to the add on creator for tweaks.
