Is there a registry key that I can get the following info from.
Total Physical memory
No registry key is needed. Just right-click on My Computer and choose
Properties. It will show you how much memory you have there.
That number is normally zero, or close to it, and should not be of any
concern to you. Despite what you may have heard, trying to make that number
bigger is not a worthwhile objective. Windows is designed to use all, or
nearly all, of your memory, all the time, and that's good not bad. Free
memory is wasted memory. You paid for it all and shouldn't want to see any
of it wasted.
Windows works hard to find a use for all the memory you have all the time.
For example if your apps don't need some of it, it will use that part for
caching, then give it back when your apps later need it. In this way Windows
keeps all your memory working for you all the time.
