The startup speed or a new instance of Internet Explorer 8 in Windows 7 may be slow and take several seconds.
One of the main causes of this slowdown can result from an add-on installed. The duration of loading add-ons is a parameter that was introduced in IE8.
Open IE8, Under Tools, select Manage Add-ons. Then select All Add-ons and check the column loading time.
A complementary module should load normally in a few seconds. If the duration of loading an additional module is too large, it is better to disable this module. IE8 will take charge when necessary to seek the add and re-submit.
If despite disabling add-ons including the charging time was set large, the problem persists, then disable one by one the other modules with the charging time is not appropriate to determine the culprit.
