The files/folders you've saved are used by the System Restore and "Add/Remove Programs" section only.. Placing them in the new computer won't install those updates correctly. To correctly install all those updates, you'll need to download their manual installers separately from their respective Microsoft Knowledgebase articles. For example, here's one such recent KB article for an update to Windows XP, as well other other operating systems that are affected by the vulnerability. A manual installer of the update can be downloaded, and saved, by clicking on the appropriate link in the article.

Although it's possible to do so, downloading them all after the fact would be extremely time consuming.. Generally, when I have such a task, we temporarily take the computer to a fast internet connection and update everything while there.. After that, we return the computer to its normal location, where transferring a few updates to the computer through a flash drive, on a monthly basis, isn't as difficult.
Hope this helps.

I copied the security updates from the C:\windows\$hf_mig$ folder, so it would be easier to recover from a system restore. My computer is old. The system restore discs were created in 2001. Since then, a ton of security updates have been released. With my dial-up connection, it takes anywhere from 21 to 58 hours to download those updates using Automatic Updates. Downloading them directly from the Windows Update site takes around 26 hours, but requires constant monitoring.
It's so much easier to have them already downloaded, but I don't know how to install them from the external drive.
If I copy them into the C:\windows\$hf_mig$ folder directly after system restore, will Windows Xp recognize them and have Automatic Updates install them?
If not, is there a way to manually install them.
