Vista, Win. Win. NET frameworks, and Office patches XP, 2. Once you have them all downloaded, you just update every patch Tuesday, and get only the changes. Though it does get the catalouges and they are getting longer every day many megs now per OSOffice rev. Once you have the files on your local machine downloaded, there is a script to make CDDVD images of them it will this automatically for DVD images per OS now if you would like. What I do is use a 4. GB SD memory card, in an SD card reader that honours the write protect tab. I used to use 2. GB cards, but I can just barely fit Win XP and most of the Office builds on it now, so I moved on to 4. GB cards. Thus when troubleshooting a machine, I trust inserting this formerly writable device into a untrusted, possibly virus infected machine since I know nothing about it, I assume it is infected knowing my device is write protected. Thus I can patch it up to date as a first step. If you use the autorun, or launch the executable on the device key, external HD, CD, DVD, wherever you wrote it it starts a script that uses the Windows Update service on the local machine to apply all the updates, but instead of going across the wire to download them it just uses the local copy. Thus it may still take 1 hours to update a Win. XP machine to the latest SP and patches, but there is zero network traffic along the way, and you can do it with the Ethernet cable unplugged entirely. Amazingly useful toolShould not run afoul of Microsoft, like the Auto. Update guys were, who were pre building a patch CD, that distributed the CD image. This tool updates scripts, and you have to go get all the patches on your licensed Windows workstation. Windows Update Cannot Currently Check For Updates Vista 32 User
