What is the purpose of this post, to share the current memory limits with the various Windows versions? I'm confused as this is posted as a question but seems to be just informational and not in response to any inquiries. Also, if this information is copied from another site please provide short description and a link to that site in the future. Thanks!
This is table is for Comparing the OS versions only, thanks for the Correction.
