It needn't be a problem. It's probably normal.

When any modern OS reads in data (i.e. the VMware executable and
the Windows OS image) the data remain in memory in case it's needed
again. For example, if you started VMware again it should come up much
faster because much may not need to be read from disc.

This extra data has no cost!

Because it's "clean", not modified WRT to what's on disc, if/when the
OS needs more RAM for something it can use any of that immediately,
because it need not be saved back to disc.

So you probably have nothing to worry about.

The laws of thermodynamics state that you can't win, you can't break even,
and you can't even quit the game.  Most human institutions are based on the
belief that you can break one of the three laws -- capitalism assumes you can
win, socialism assumes you can break even, and religion assumes you can quit
the game.
