I downloaded an installed IE7 Beta 2 to check if the site I look after was compatible (small risk, but a large impact if their was any problems). The site looked fine, but I never really got in to using IE7. Now I need to uninstall it, so that I can go back to a more stable IE6.

I found the following uninstall instructions from the IE Blog.

To uninstall Internet Explorer 7 Beta 2 Preview and return to Internet Explorer 6 on Windows XP

1. Click “Start,” and then click “Control Panel.”
2. Click “Add or Remove Programs.”
3. Check “Show Updates” at the top of the dialog box.
4. Scroll down the list to “Windows XP – Software Updates,” select “Internet Explorer 7 Beta 2Preview,” and then click "Change/Remove."

If "Internet Explorer 7 Beta 2 Preview" does not exist, run %windir%\\$NtUninstallie7bet2p$\\spuninst\\spuninst.exe. You need to have "view hidden folders" enabled. %windir% is your Windows installation directory, which is normally 'C:\\Windows' on most systems.

Hope this helps - Oliver
