Something you should know.......
Because Internet Explorer is an update, IE11 will be offered to you again in Windows Update.
If you have Windows Update set at Automatic install, it will get re-installed before you know it.
Therefore, you need to do the following 2 things.......
1. Set your Windows Update to Manual.
To set Windows Update at Manual will give you option to install or not to install.
Start > in the search box, type windows update > press Enter > left side, click Change Settings > under Important Updates, click the pointer and change it to " Download updates but let me choose whether to install Them " > click OK when done.
2. When IE 11 shows up again in your Windows Update, " hide " it so that it will never appear again.
