Can I add more RAM to my 32 bit Operating System (OS)?

Some 32 bit Operating Systems (OS) limit the amount of RAM they will support. Exceeding that limit may contribute to a number of problems. Therefore it is not supported. Upgrading to a 64 bit Operating Systems (OS) is recommended. A list of 32 bit Operating Systems (OS) with limited RAM is below.
