Virtual memory is a clever trick that Windows uses to supplement your computer’s RAM. When RAM runs out, your system starts using part of your hard disk as a temporary memory extension. This ensures that your applications continue to run smoothly, even when RAM is running low.

By default, the amount of virtual memory allocated may not be sufficient for all your activities. This leaves you with a sluggish PC, applications that close without warning and, let’s be honest, an urge to throw everything out of the window. Fortunately, increasing the amount of virtual memory is child’s play, and I’ll take you through it step by step.

  1. Enter Windows 11 Settings.
  2. In System, click on System information.
