I too would like to know how to uninstall IE9BETA, because I want to install the RC.
Here is the problem I'm having. Whether or not I use the individual downloads or windows update, the installation for Internet Explorer 9 RC fails.
Here are screenshots of trying to do this via Windows Update:
Shows only 1 Update available
Shows Internet Explorer 9 installation failure
Some update were not installed
Clicking on "Try Again" as shown in the above screenshot does not work. The installation perpetually fails, and each time it does so, it adds (or updates) a shorcut on my desktop,
Internet Explorer Troubleshooting. I've followed all 5 methods given in the article, all to no avail.
Internet Explorer 9 RC just flatout refuses to install.
Now I know jujst about every "Uninstall IE9BETA resource says to go to View Installed Updates, including the SevenForums tutorial
Internet Explorer 9 Uninstall, except that
Windows Internet Explorer 9 does not show up in the list of installed updates.
So I figured that this is perhaps because of
KB2482017 (Cumulative Security Update for Internet Explorer 9 Beta for Windows 7 for x64-based Systems)
KB2482017
So perhaps uninstalling KB2482017 first might help? But that particular update also does not show in the list of installed updates.
I've tested my IE9RC downloads in a Virtual PC installation of Windows 7, and it works flawlessly. I just cannot install into my production machine, Prometheus.
So what I'm looking for is another way of uninstalling Internet Explorer 9 BETA, perhaps something from an elevated command line, that will revert my system back to Internet Explorer 8.
