everytime i have had update problems from msquish, it’s been b/c of a damn ie update.
You're not the only one, mate. I have it turned off on all personal machines that (dual-)boot the 'doze OS, and strongly suggest to customers that they do the same.
Although I did start a thread not too long ago about how a recent 'upgrade' from MS was proving remarkably helpful for many and even considered running it on the machines here for that very reason.
Found it, although it relates to XP and not IE specifically.
