Let’s say you just decided to reinstall your machine. You pull out your Windows XP installation disk, install Windows XP, Service Pack 2 from disk. Then you connect to WIndows update to install updates.
You’re about to break your machine, but only a little.
See, there’s an update to Windows Update that has to be installed before you do anything else. However, after you apply this update, the next thing Windows Update is going to do is download and install Windows XP Service Pack 3. If you didn’t perform a reboot in there (and why should you, it didn’t ask you to), installing Windows XP SP3 breaks your ability to automatically update. The reason:
The latest version of Windows Update includes a file that was not available in the release version of Windows XP. This file is named Wups2.dll. Therefore, after the repair operation (or reinstall) is complete, the following situation exists:
• The Wups2.dll file remains on the computer. • The registry entries that correspond to this file are missing.
Because the registry files that correspond to the Wups2.dll file are missing, update installations are unsuccessful.
Microsoft hasn’t messed up something like this in a while, tisk tisk.
