vLite, currently in beta, is a free software for customizing the Windows Vista installation. The idea is that Windows Vista installs everything by default, some unneccesary. And so, this tool lets you pick ONLY the components that you require. The end result is a smaller installation size, lower resource usage post-installation and a faster operating system.
What you can do with vLite:
- remove components
- integrate drivers
- split/merge Vista installation discs
- apply tweaks
- make bootable CD/DVD
The only drawback is that you have to recompile the installation disc ISO, burn it onto a CD/DVD and reinstall with your customizations.
