Is it necessary to reboot the PC after upgrading the ActiveX control?

If you have been browsing a device that is using an old ActiveX control then switch to a device with a new ActiveX control in the same browser session, after installing the new ActiveX control you will be prompted to reboot your computer before the changes will take effect. In fact, you only need to close all instances of Internet Explorer, then open a new instance and browse to the device with the new ActiveX control. This time, after installing the ActiveX control, you will not be prompted to reboot your computer.
