## Service Packs and Hotfixes

As with UNIX, Windows NT has patches and fixes to address problems discovered after a major OS release. These currently take two forms: service packs and hotfixes.

#### Service Packs

Windows NT Service Packs are extensive collections of patches and hotfixes that solve problems with the base operating system and optional software. Service packs also include additions and enhancements to the operating system.

Every service pack includes all previous service packs, so you only need to apply the latest version. It is standard practice to install service packs as they become available, even if they do not solve an existing problem. After installation, the service-pack version can be displayed from within the graphical user interface (GUI) and it is also displayed during the boot process.

#### Hotfixes

Windows NT hotfixes are patches that perform a specific software function or package. They typically are applied only when they will solve an existing problem. This includes a security hole or even a problem caused by a service pack. You can obtain a list of installed hotfixes using the hotfix command.

#### Obtaining Service Packs and Hotfixes

Service packs are obtained through Microsoft.com. They need to first be downloaded, and then the service pack can be installed from the resident computer.

Hotfixes are a solution to a specific problem. They are created and distributed through Microsoft Technical Support.
