Some machines (including mine) started to get this prompt frequently after upgrading from Windows 8 to Windows 8.1.
My machine has 16 GB RAM. When this happens, there is still a few GB free memory. It is not related to any specific application. It seems to be
the case for others experiencing the same problem. Some W8.1 users never see this.
I am wondering if anyone could share some insight into this issue, especially any tips to prevent this.
