Anyway, I am noticing this right now.

With several applications running, including a couple ones running by means of a DOS-window, one might guess or suspect that when RAM memory becomes full or saturated, it is no more and you are reaching an end point.

Only 8 GB of RAM installed. I have received the 16 GB memory upgrade.

So how about the possible capabilities of Windows switching between tasks by means of using the disc instead for this purpose?

Is there something built into the operating system which eventually makes this possible?

Of course there needs to be enough space for this to happen if it does at all.

Anyone having an answer to this question?

Thanks!

Yes, it's called a "swap file" or "virtual memory", and it's been used - silently and transparently - by Windows for a couple of decades now.

Edit - the process is also known as Paging, and was first introduced in the computer world with the Atlas over half a century ago.
