Why is memory leak so bad?
Memory leaks are bad because your program claims resources and keeps them occupied for its entire lifecycle, even though it does not need them anymore. If you have a static leak the size of X when the program starts and it does not grow over time it’s unfortunate, but probably not the end of the world.
Why is my Excel taking up so much memory?
The reason for this is that Excel has its own memory manager and memory limits, regardless of the memory capacity of your machine. In fact all the Excel versions after Excel 2003 were designed to use a maximum of 2GB memory. So while your computer may have 4GB or even 8GB RAM, Excel can only use 2GB of that.
How do you fix a memory leak problem?
If you have a memory leak and get to the point of almost running out of memory, the normal procedure is to reboot the machine in order to clear out the memory. You can use RAMMap to clear areas of memory negating the need to reboot the machine.

Why is Excel so hard to test for memory leaks?
Sadly most desktop applications are never fully tested for memory leaks because memory is cheap and a computer is often switched off or rebooted.
