Yesterday, users deploying what seemed to be a newer version of IE7 with their WSUS server, ran into problems. The update, despite no indication of it being a Spanish version, was either automatically approved to be installed or ready to be approved when admin's of WSUS servers came to work after the syncronisation.
When the update went out to users - if it was being installed interactively, it would pop-up a spanish message [most likely relating to the version of windows not being in spanish]. In the situation where it would install without user interaction such as during shutdown, the user would find that when they came to their computer, it would be stuck installing this update [of course, this would be because the error message had appeared, but with no way of clicking the OK button] and the only way out would be to power down the computer.
Both the working version dated 1st Nov 06 and the new faulty version dated 21st Nov 06 have now become expired [for XP only so far - the newer 2003 version remains and I haven't personally used it as I installed the original version] so be sure to decine just the newer version if you can, as if you have already approved the update for installation and declined its predecessor [or have just declined the older version], you will have to wait for a new version to surface.
