Microsoft published the Internet Explorer 7 Deployment Guide, a 67 page Word document, discussing how to plan and carry out IE7 deployment. I just skimmed over the document, but it seems to me that more things have to be considered than what I thought before.

Originally, I planned to deploy IE7 at the beginning of this year in our organization, but then we found out that some of our applications are having problems. Among them is an issue about certificates with Citrix Presentation Server. All these problems are probably solvable, but this costs time.

I still have much respect for this update. The stand I took in the discussion on 4sysops a while ago remains. We will certainly not deploy IE7 on all of our machines at first. In these cases we always let typical users test the new software thoroughly before the major rollout.
