Understanding windows update process

[bflare]

I have downloaded windows updates via the msfn hotfixes page, which directs me to the microsoft page on which i download them from. A typical downloaded file is: WindowsXP-KB899591-x86-ENU. The file type is an application. Do i just insert these files into the HOTFIXES & UPDATE page of Nlite?
