Before you take your computer to an expensive tech expert or waste the time necessary to format the computer entirely, check to see if an Active X update is all you need to solve your computer issues.
In most cases, there is nothing else the user must do to complete the update other than restarting the web browser.
The first and simplest is to simply reinstall the browser.
This is by far the fastest way to solve the problem, particularly if you are using Internet Explorer.
Update (October 11, 2016): As of today, out-of-date Flash Active X control blocking for IE11 is live.
The blocking period will continue till November 10, 2016.
By default, Windows Update will automatically install important Flash updates as they become available for Internet Explorer and Microsoft Edge on those systems.
