I've encountered something very odd while using my pc&laptop and have no clue why is it happening. Apparently both my pc and laptop seem to use much more ram than the sum of all processes in task manager. For example now, task manager tells me that 77% of memory is being used(around 12,3GB of my 16GB), but all of the processes don't use up more than 7GB. Im uploading clip for reference. Any help/explanation would be greatly appreciated.
Don't worry about RAM. You bough that amount of ram for what? For ramdisk only so you must use it by yourself and control? No, more ram is used by system, not only for running processes, but for better Windows experience. It was explained lot of time over internet. If you have 4 GB of ram and you see that you have 1 GB free, then don't expect that if you buy another 4 GB, you'll get 5 GB free. No, Windows will use it if possible for different purposes and free it when user's process need it. And you should be happy - you bough that memory so it will be waste of money if it will be used rarely, isn't?
