Most recently, Windows 7 frequently prompts you because there are many programs open at the same time: The computer is running out of memory, such as:
Cause of the problem:
After some attempts, a general conclusion is drawn: when the size of the virtual memory space is smaller than the size of the physical memory space, once the program is open too much, the physical memory is full, it will prompt the computer is out of memory.
But it should also hint that the virtual memory is not enough, but just hint that the computer is running out of memory!
Workaround:
If you have only one type of hard drive, actually select "Automatically manage paging file size for all drives" on it;
My case is that there is an SSD, and a plain hard drive,
So I want to prioritize the use of SSDs, because the speed of SSDs is basically as fast as memory;
So I set the SSD to a custom size, and then other normal partitions Select "System managed Size".
