Software remastering is the process of customizing a software or operating system distribution for personal or "off-label" usage. The term remaster is taken from the remastering in audio production process. The term was popularized by Klaus Knopper, creator of the Knoppix live distro, which has a tradition of encouraging its users to hack the distribution in this manner to suit their needs.
Software remastering is particularly associated with the GNU/Linux distributions. Most Linux distributions started as a remastered version of another distribution. Notably, remastering SLS Linux forked Slackware, remastering Red Hat Linux helped fork Yellow Dog Linux and Mandriva and TurboLinux, and by remastering a Debian distribution, Ubuntu was started, which was itself remastered to make Linux Mint.
Microsoft Windows has also been modified and remastered. Various utilities exist that combine Windows updates and device drivers with the original Windows CD/DVD installation media, a process known as slipstreaming.
Many video games have also been either modified (see modded) by upgrading them with additional content, levels, or game features. Notably Counter-Strike was remastered from Half-Life and went on to be marketed as a commercial product.

Software remastering creates an application by rebuilding its code base from the software objects on an existing master repository. If the "mastering" process assembles a distribution for the release of a version, the remaster process does the same but with subtraction, modification, or addition to the master repository. Similarly a modified makefile orchestrates a computerized version of an application.
When an amount of unneeded code is "cut down" to some wanted minimum it removes unwanted features that the original publisher and maintainer needs. When new features are added it evolves the software. A remastered version may consider that a feature of the original is a bug, and provides a modified copy of the feature that works in a better way.
When it is published a software remaster maintains the integrity of the named product from which it was derived by adherence to a shared software repository with any modifications, and with the intention of maintaining the good name needing approval. If approval does not happen, the name and the repository have the option to become their own master. The creator of a published software remaster, if they do no further work to evolve the software, must at least arrange for maintenance support channels, such as updating user documentation, providing a forum, an internet relay chat line, or a wiki, providing intent to maintain a version for the life of its usefulness.
Remastering centers around the reputation of a product, and so the distribution process requires an official, sanctioned version. This differs from the attitude in much free software in the many cases where the name of the product is "cheap" because plentiful and stable, where no guarantees or liabilities are offered, and where permission is inherently granted to redistribution any modified version under any name.
The original repository is the master, from which creative flavors and spins may already be offered by the original producers. A remaster production supports any additional software from outside it, supports the new mixture of software from the original repository, or keeps the modifications of original masters on the outside the master repository. Software remastering is tolerated by the maintainers of the master repository, while free software modifications are encouraged by the same social conventions.
A remaster is a personalized version of PCLinuxOS created according to the needs of an individual. It is created using the mklivecd script applied to its installation, which can be of any of the official flavors of PCLinuxOS. An official remaster can only include software and components from the official repository (version control).
A community remaster may contain software and components from outside but should not have any reference to PCLinuxOS other than "derived from PCLinuxOS" or "based on PCLinuxOS" if intended for distribution. There have been several of these third-party distributions over the years, though they may only mention that connection if they follow strict guidelines concerning the quality, maintainability and distribution channels, all subject to approval from officiating members of the forum.
PCLinuxOS Gnome Edition is an example of a remaster.
PCLinuxOS and Unity Linux are Mandriva-based. Unity Linux is intended as a base platform that acts as a distribution "template" that ensures interoperability between packages, and upon which one is encouraged to remaster any "all new" GNU/Linux OS distributions.
The examples in this section show some historical and operational aspects of the software remastering as it has occurred with Microsoft Windows.
98lite is a remastered edition of Windows 98 and Windows Me without Internet Explorer, written by Shane Brooks. It was written in response to Microsoft's claim, in antitrust proceedings, that IE is integrated into Windows and cannot be removed without breaking other features.
98lite was created in 1998 after the original release of Windows 98, out of necessity, since at the time Brooks had a slower laptop computer that ran the Windows 95 operating system fine but Windows 98 was simply too slow. Brooks liked the stability Windows 98 offered as well as some of the new features but had no need for the Internet Explorer browser. The original 98lite was a simple DOS based installer that ran before the Windows 98 installation, this installer made modifications to a fresh installation of Windows preventing the installation of Internet Explorer and the Active Desktop.
Installation of the first release of 98lite required the user to extract certain files from a Windows 95 disk as 98lite uses the Windows 95 shell. A second program called Shell Swap swapped the Explorer shell with the Windows 95 Explorer, which does not contain the web features of Me's and 98's Explorer and is therefore considerably faster and more lightweight, this was designed for existing installations of Windows 98 where the original 98lite was designed for a new installation of Windows. A third program converted "required" components into addable and removable options.
With version 2.0 of 98lite, the three programs were merged and combined into a single program. The IE remover was combined with the components converter, making IE uninstallable and reinstallable with the Add/Remove Programs control panel applet as with the other components, the user could also choose the Windows 95 shell and keep Internet Explorer installed. The user now had three installation options, the "sleek" option allowed the user to install 98lite with the Windows 95 shell like in the original release or the user could choose "chubby" which used the Windows 98 shell with some Active Desktop features disabled. The final option was "overweight", which installed 98lite with the Windows 98 shell and nothing disabled but Internet Explorer still removed. Version 3.0 added support for Windows 98 Second Edition, an upgraded version of Windows 98 with Internet Explorer 5.0 which made 98lite 1.0 through 2.0 obsolete. The current 4.x line has many improvements, including bugfixes and support for Windows Me.
Installing any version of DirectX under 98lited Windows requires at least temporary presence of PC Health. Otherwise DirectX refuses to install, finishing installation attempt with error message "DirectX did not copy a required file".
Revenge of Mozilla
Revenge of Mozilla is another, free, application that removes Internet Explorer from Windows 98 and restores the Windows 95 explorer.exe. There are two versions of this, one for the original Windows 98 release, and another for Win98 SE; there is no version for Windows Me. This is no longer supported, and not being updated.
There is also a company spun off from Lite-PC that produces Windows 98 and Me installations which are small enough to easily fit on embedded microchips; as small as 8MB, using 98EOS. There are also many free alternatives to this, such as Mindows and Nano98, which can provide either smaller file sizes, or more broad functionality.
Windows 2000 and later
The creator of 98lite also build a similar utility for Windows 2000 and Windows XP, called 2000-XPLite, which removes Windows components that are not intended to be removable. This includes Out-Of-Box Experience, Internet Explorer, Outlook Express, Windows Media Player, and others. 2000-XPLite also allows tweaks to the Operating System to enhance its performance.
2000-XPLite does not use a text interface as did 98lite. Like 98lite, 2000-XPlite installs Windows with all components, and then removes unwanted components after installation.
nLite is a free application for Windows 2000, Windows XP (32 and 64 bit) and Windows Server 2003 designed to remove unwanted Windows system components, and create cut-down customized installation CDs (or bootable USB sticks), build by Dino Nuhagic.
nLite prevents components from being installed rather than removing them from an already-installed system.
It lets users add device drivers and integrate Service Packs and other Windows Updates into their installation media. It also allows customization of the installation, including Product Key entry, administrator's password, regional settings and creating user account names. Users can also remove hundreds of drivers aimed at obsolete hardware that slow down the normal install process. Since the installer does not contain the unwanted components, this leads to major improvements in the speed of installation, which is of considerable benefit to IT Staff still using a manual 'roll out' approach (without the benefit of Microsoft Sysprep). Such software-minimized CDs also allow Windows to be installed on hard disks below 512MB in size.
HFSLIP is an open source command line Hotfix and Service Pack slipstreaming utility designed to update Windows 2000, Windows XP, and Windows Server 2003 installation sources. In addition to hotfixes and service packs, HFSLIP slipstreams other Microsoft updates such as Internet Explorer, DirectX 9.0c, Windows Media Player, and Windows Media Codecs. It also integrates third-party device driver updates, including DriverPacks.
HFSLIP slipstreams (replaces) the original files with the newer versions found in the updates from the Microsoft Download Center. HFSLIP places hotfixes that were non-standard or required a special installation procedure in the SVCPACK folder, to be installed automatically near the end of Windows setup.
As of May 2010, HFSLIP is no longer being developed, and the main website was taken down.
The main interface of Autostreamer is a wizard which guides the user through the slipstreaming process. According to PC World, it "simplifies the once-intimidating chore of slipstreaming your Windows XP CD—producing an XP SP2 CD from your SP1 or even vintage original XP CD".
Collections of device drivers are called DriverPacks. These exist for CPU Chipsets, CPU, Graphics/Video, Ethernet, Mass Storage/Removable/USB, Audio/Sound and Wireless (Wi-Fi/WLAN) hardware. DriverPacks BASE is a tool that integrates all DriverPacks into one, "uniform" Windows installation CD, which works on every piece of hardware, and needs no additional device drivers after the installation.
Windows Vista and later
Some people have reported success using vLite with Windows 7,[dubious ] vLite is not fully compatible with Windows 7. To date the creator has not announced any intention or plan to support Windows 7.
Win Toolkit can create a cut-down customized installation CD (or bootable USB stick) for Windows 7 and later versions.
