Paging file size not updating
With virtual memory, Windows temporarily move some data from the RAM to a paging file on your hard drive if your computer doesn’t have enough physical memory to run a program or operation.
You can limit how much space this paging file takes up.
When your system runs low on RAM (Random Access Memory), it will move some memory to in order to run smoothly. RAM is used to store all kinds of data that you are using, like running files and programs.
Our computer stores these data in RAM because it is much faster to read from RAM than to read from hard drive. When RAM is running up, System will identify the data that you don’t use any more or use not too much, then move these data to pagefile. For instance, if you are using Chrome and some web pages are minimized, they are doing nothing but still taking much memory.
You can close the useless programs through Task Manager.1).
Press Ctrl Shift Esc keys together to open Task Manager.2). In this tab, you can see how much memory that running applications is taking up. Choose a program that you don’t use but stays on and click End process.
Virtual memory combines your computers RAM with temporary space on your hard drive.
When RAM runs low, virtual memory moves data from RAM to a space called a paging file.
Disabling the file may even cause serious system problems.
The Virtual Memory Paging File is , you can place the page file on a second physical hard drive instead of the same C: drive that Windows is on.
Doing this allows Windows to dump temp junk onto one drive while not having to interrupt reads or writes on the other drive.
This will show you how to manually change the size of virtual memory if the default size is not enough for your needs, and how to change what drive is used for the paging file.
