Remove Consecutive Duplicates Only

I'm having a "challenge" in Excel.

I've got two columns in Excel with data in it.

Column A is unique data and consists out of date and time and Column B is data which indicates the state of an application.

So every task the application is performing gets logged every minute so Column B is showing duplicates.

Now what I want to do is to remove the duplicate actions but only if they are subsequent. So an action can happen several times a day but only once in an hour. But if I use the AdvancedFilter with the Unique Records only, it removes all the duplicates also from later on the day and that is not the intention.

So I would need a macro for it. My problem is that I somewhat know how it should work, but I don't know the syntax to write it. So it should be something like If the data on the next line is the same as the current, then remove the next line, if not go to the next line and check again.
