If you are going to install many applications and updates that require a restart, you can "batch" these. If you are given the option to either "restart now" or "wait until later", you may (within reason
, that is) install several applicatins (or patches) and then restart your computer to complete their installation (obviously they will not function until you do so) into the Windows operating system files.

"Installing a Graphical Identification and Authentication dynamic link library (GINA) requires a reboot. The GINA is a replaceable DLL component that is loaded by Winlogon. The GINA implements the authentication policy of the interactive logon model, and it is expected to perform all identification and authentication user interactions. For example, replacement GINA DLLs can implement smart card, retinal scan, or other authentication mechanisms in place of the standard Windows XP user name and password authentication."http://www.microsoft.com/winlogo/software/windowsxp-sw.mspx
