## After a Windows NT Computer Is Installed

After Windows NT is installed on a computer, you may have to recheck it for the following reasons:

- Installing optional system components.

Most optional Windows NT components install a service and can include new Help files, a new administration tool or control panel utility, or add menu items to an existing tool or the Control Panel.

- Applying operating system (OS) service packs and hotfixes.

There are always new patches for bugs and security problems as they are discovered.

- Making OS upgrades.

In most cases, it is be possible to apply the upgrades to an installed system and keep existing settings without reinstalling them from scratch.
