title: How to increase the size of physical memory in windows 7 32 bit OS
body: <p>I have a total 4 Gb ram and I had installed a Virtual box and had assigned it 1.5 Gb memory. But now my applications in windows are reporting "running out of memory". So i changed the setting in Virtual Box to use 512mb of memory. But still the Task manager in Windows shows only 2Gb of physical memory.
  I have tried a couple of ways mentioned to increase virtual memory in Advanced system property but that doesn't help either. So i want a way to increase the ram size allocated to windows.</p>

  <p>Thanks</p>
