It looks more likely that this option to install IE9 without a reboot is a new feature of Service Pack 1. I have now repeated this process on a Windows Server 2008 R2 SP1 and Windows 7 SP1. (see images below).ĭisclaimer: I have only seem this behaviour on one computer so far but I am testing it one more really soon.
Therefore it seems that with Windows 7 / 2008 R2 Service Pack 1 installed it is now possible to install IE9 without a reboot. Previously I have installed IE9 on 3 Windows 7 computers that were not running service pack 1 however they all required a reboot to install IE9. I have just install IE9 on a Windows 7 and a Windows Server 2008 R2 computer running Service Pack 1 and I was very pleased to see that in both cases it does not required a reboot to install. Therefore it would still be prudent to plan for a reboot but not always expect it to happen.
This seems to be dependent on what application you are running at the time. Update: Now that I have installed the final version of IE9 on 6 computers 2 of them needed to rebook so it would seem that it may or may not require a reboot.
