The No Add-ons mode allows Internet Explorer to temporarily run without any add-ons like Toolbars, ActiveX controls, etc. The No addons mode in Internet Explorer is rather useful when you want to troubleshoot incompatible browser add-ons or extensions. It is also very useful when you want to troubleshoot a problem like say freezing of your IE, to identify whether it is related to any add-on.
Open a command prompt windows, type the following and hit Enter, to open IE in No addons mode:
“%ProgramFiles%\Internet Explorer\iexplore.exe” -extoff
Then if you need to, the through Internet Options > Manage Add-ons, you can enable or disable each add-on to identify which, if any, add-on is creating problems.
