ActiveX controls are small applications that Web sites can use to deliver content such as videos and games. You can also interact with content such as toolbars and action tickers while browsing the Web.

However, these applications may not work or provide content that you do not want. In some cases, these applications may be used to collect information from your PC, damage information on your PC, install software on your PC without your permission, or allow someone else to remotely control your PC.

A common cause of runtime error 7 is problems in the Windows registry. The registry, if you don’t know what it is, is basically the central database that stores all the important hardware and software parameters that the operating system recovers each time the end user tries to run an application.

Registry data is often corrupted by constant writing and rewriting of data, resulting in system performance degradation and a large number of errors.
