Not unless it breaks, and even if someone already has upgraded it and it costs 5k to upgrade and the old system still works it won't be upgraded.
Point is, its now unsupported, so its good as broken... In fact, if you need win 95 to run it, its been broken for a long time now. The longer you delay that upgrade, the harder it becomes. This is one reason I now I insist all our clients upgrade as each new os/dev upgrade occurs. Its much cheaper in the long run that way.
