IE11 for Windows 7 serial Uninstall

Previous Windows support for the previous version of IE will not be more than three (for example: IE 4/5/6 for Windows 98, ie 6/7/8 for Windows XP, ie 7/8/9 for Windows Vista), but with the current version of IE With the speed of change, and with the release of the IE11 standalone installation version, the version of IE supported by Windows 7 has reached an unprecedented four versions (IE8/9/10/11).

Since Windows always has only one IE version at a time, and different versions of IE cannot coexist, for Windows 7, the four versions of IE8/9/10/11 can only exist, and once a higher version is installed, you cannot run other versions of IE's installer. If we uninstall all the high version of Ie,windows 7, it automatically restores its default built-in version of IE8. Also, when we install Windows 7 completely, we can either install IE9 or IE10 First, then install IE11, or install IE10 directly without installing IE9 or IE11.

The author has previously mentioned in the "detailed Windows 7 system ie8/ie9/ie10 Three versions of the relationship", Windows 7 adopted a similar to Windows Xp/server 2003, only the highest version of the uninstall program of IE. That is, even if we installed IE9 or Ie10,windows 7 before installing IE11, the IE11 will only be displayed in the Installed Updates list after the IE11 is installed, and it will not show IE9 or IE10 previously installed, unlike Windows Vi Sta. Windows Vista If you installed the IE8 and then installed the IE9, the uninstall program for IE8 and IE9 will also appear in the Installed Updates list.

As a result, installing IE11 in Windows 7 May experience several uninstall situations:

★ If you have not previously installed IE9 and IE10,IE11 from IE8 direct upgrade from:

After you install IE11 in Windows 7, the "Turn on or turn off Windows features"-"Installed Updates" list in Control Panel displays the IE11 uninstall option, which can be automatically rolled back to IE8 before the installation of IE11.

However, this IE11 uninstall option cannot be rolled back to IE9 or IE10 because we have never installed IE9 or IE10. IE9 or IE10 cannot be installed directly if the IE11 is already installed. So if we want to install IE9 or IE10, we can only uninstall IE11 restore IE8 before installing IE9 or IE10.

★ If you have previously installed IE10 but have not been installed IE9,IE11 upgrade from IE10:

After you upgrade a previously installed IE10 to IE11 in Windows 7, the "Turn on or turn off Windows features"-"Installed Updates" list in Control Panel will no longer show the IE10 uninstall option and replace it with the uninstall option to display IE11. However, while the IE10 uninstall option is hidden but still present, if we uninstall Ie11,windows 7, we will automatically restore IE10 instead of the default IE8. Uninstall IE11 cannot be rolled back to IE9 because we have not installed IE9.

★ If you have previously installed IE9 but have not been installed IE10,IE11 upgrade from IE9:

When you upgrade a previously installed IE9 to IE11 in Windows 7, the "Turn on or turn off Windows features"-"Installed Updates" list in Control Panel will no longer show the IE9 uninstall option and replace it with the uninstall option to display IE11. However, while the IE9 uninstall option is hidden but still present, if we uninstall Ie11,windows 7, we will automatically restore IE9 instead of the default IE8. Uninstall IE11 cannot be rolled back to IE10 because we have not installed IE10.

★ If previously installed IE9 has been installed Ie10,ie11 is from IE9, IE10 all the way to upgrade to:

If the IE11 is an upgrade from the IE9 and IE10 installed from this point forward, the "turn on or turn off Windows features"-"Installed Updates" list in Control Panel will hide the IE9 uninstall option after the IE10 is installed, hide the IE11 uninstall option after installing IE10, and display IE 11 to replace the uninstall option. However, the IE9, IE10 uninstall option is hidden but still exists, and we can uninstall the IE11 and roll back to the previous version.

This kind of serial unloading must be carried out step-by-step. Recovery IE10 need to be uninstalled once (uninstall IE11), restore IE9 need to uninstall two times (uninstall IE11, IE10), restore IE8 need to uninstall three times (uninstall IE11, IE10, IE9).
