How to use the 12gb completely
We have set the OS Virtual memory to 4092-8184 in C & E drives (only C & E drive in server)

If Windows is using all the memory, what will Oracle use?

Why do you want Windows to use all the memory?

As screen shot your memory utilization is good. If you utilize 12 GB completely you will be get system slowness, unexpected reboot, server hand like problem. If process require more ram system itself provide the extra ram to process.

Windows is using the complete 12 GB of memory as indicated in screenshot 1. The 8 GB is the amount Windows has allocated at the moment to the system cache. You should check the memory settings for the Oracle database system, if you suspect that the database isnn't using enough memory.

Why do you keep your pagefile so small? In your situation you could easily go with system managed or allow 12 GB on drive C:.
