The Offline Updates tool has been updated to include the option to
install IE7. If you select to install IE7, the autoinstaller will
install ie7, reboot, then continue to install all remaining updates.
If you dig through the file structure you can move the already downloaded updates to the new versions folder structure.
Biggest folders to copy are the OS you downloaded for. I.E <drive>:\ctupdate32\ctupdate30\client\wxp (or/and w2k, w2k3, win)
Once you have copied the folders over you can launch DownloadStarterGUI.exe from the root and it will check to see what updates are downloaded and download whatever else is needed.
Also, don’t forget to copy your exclude files if you use them.
