Service Packs and Updates

Most, but not all of the updates can be downloaded and saved.

2 ways.

1. click on the read more link on each windows update items. This will open a window with the details on the update, and "usually" includes a link to download the update.
2. Go to the downloads page, select your operating system and software, review the list, and download the updates that relate to your needs.

I should have been clearer in my first answer.

When you use either Windows, or Office update, the files you download are temporarily stored in one of several places.
C:\Windows\Windows Update
C:\Windows\Temp
C:\Windows\Temporary Internet Files
Once the install starts, the new files are extracted from the archives, and directly replace the older versions of the files.
As Update has installed all the files from an archive, that archive file (what was downloaded) is usually deleted.

Update also modifies the Windows Registry when it installs updates. So even if you kept track of what files changed in ALL of the folders, you still would not have the complete update.

As I stated in my first answer, the only way to save updates forfuture use, is to manually download and install each update.

There is a link for IT managers from the Windows Update page.
It lists updates by Windows version to download. Again, you have to manually download and install each update.
