PageDefrag
One of the limitations of the Windows NT/2000 defragmentation interface is that it is not possible to defragment files that are open for exclusive access. Thus, standard defragmentation programs can neither show you how fragmented your paging files or Registry hives are, nor defragment them. Paging and Registry file fragmentation can be one of the leading causes of performance degradation related to file fragmentation in a system.
PageDefrag uses advanced techniques to provide you what commercial defragmenters cannot: the ability for you to see how fragmented your paging files and Registry hives are, and to defragment them. In addition, it defragments event log files and Windows 2000/XP hibernation files (where system memory is saved when you hibernate a laptop).
PageDefrag works on Windows NT 4.0, Windows 2000, Windows XP, and Server 2003.

Features:
- hotfix, language pack and driver integration
- component removal
- unattended setup

Windows Vista from Microsoft takes a lot of resources, we all know that. vLite provides you with an easy removal of the unwanted components in order to make Vista run faster and to your liking.
This tool doesn’t use any kind of hacking, all files and registry entries are protected as they would be if you install the unedited version only with the changes you select.
It configures the installation directly before the installation, meaning you’ll have to remake the ISO and reinstall it. This method is much cleaner, not to mention easier and more logical than doing it after installation on every reinstall.
