IE 8 is integrated with Windows XP and cannot be upgraded to a later version. In this case, the only alternative to surf safely on the Internet would be to use other navigators, like Firefox or Chrome. Internet Explorer 11 requires Windows 7 with Service Pack 1 and doesn't work in older Windows versions. Even when I use Windows 7, I always surf on the Internet using Firefox.

In the scheme of things, those using older versions are likely locked into older hardware and os. That number will continue to decline as the hardware eventually fails and replacements will enter as newer, more updated machines/os.

Where this does present problems is the CONTINUED use of ie6 in some enterprise level organizations who either refuse, or cannot (usually due to budgetary reasons) to upgrade both hardware and os/apps --- For those folks I have no sympathy.

Meanwhile, even using Firefox will mitigate exposure to exploits by only so much: some versions of FF will not run on older hardware, and Chrome is not that much better for legacy machines.

The march of time will correct all these ills, and at the same time introduce new ones, so in the circle of "life" the threats continue.

Older operating systems like XP are no longer supported by Microsoft, so it makes little sense to also support the browsers that operate on them. You're taking a risk using those older operating systems and browsers. If you must continue to use these systems then Microsoft is giving you little option but to upgrade (or move to another OS).

You can still drive antique cars that were made before the requirements for seat belts came into effect, but you're taking the risk of an accident...
