Internet Explorer 7.0 High Priority Update

Just a quick update with more recent numbers. As of today (Nov. 6th), MSIE 7.0 share is still around 26% of all MSIE users who visit About 50% of our firefox users use Firefox version 2 (40% use 1.5 and the remaining 10% use various older version). So it looks like only a small number installed MSIE 7 after it became a high prioirty update. But then again... this is for, not an average web site. If you are willing to share logs from an "average" (= consumer oriented) site, let us know.

Alex was the first reader to report that Internet Explorer 7.0 is now a high priority update on Windows Update. Unless you setup the respective blocking script, expect IE 7 to be installed on your systems if they are configured to retrieve and install high priority updates from Windows Update.

The update is still interactive. You will not just come back to your system and find IE7 all ready to go.

For (which is probably not y our typical site), 50% of Firefox users already use Firefox 2.0, and 23% of Internet Explorer users use MSIE 7.0. Overall, we got about a 50/50 split between Firefox and Internet Explorer users.

I will keep the table below updated throughout the day to see if this changes the uptake of MSIE 7.0 for our users (the data comes from Google An alytics, which we use for our web stats tracking)
