These next steps are known as "Clean-booting" your computer and will disable all programs and services that start with your computer that are not the basic Microsoft services. During these steps, please pay special attention to the note that will inform you how to reverse these changes if you so choose. You do not need to reverse these changes and no program on your computer is deleted. They simply do not start, when your computer starts; you will need to manually start them.

Follow these instructions from Microsoft on "Clean Boot"

Additionally, before closing the MSConfig tool, you may need to click on the "Startup" tab and disable startup programs.

Please be aware that many anti-virus software packages will not be disabled by the clean boot and may still be active and blocking the game. We advise you to turn off anti-virus software manually after the clean boot in order to make sure that it is not the source of the issue with running the game. You should remember to turn your anti-virus software back on as soon as you have finished troubleshooting.

After clicking Apply and Ok, you will need to restart your computer. When the computer boots, open the ESO Launcher and use the game repair feature.
