  3. In the Action pane, under the virtual machine name, click Settings.

  4. In the navigation pane, click Memory.

  5. On the Memory page, set the Startup RAM to at least 2 GB and then click OK.

Increase the memory using Windows PowerShell

  1. Open Windows PowerShell. (From the desktop, click Start and start typing Windows PowerShell.)

  2. Right-click Windows PowerShell and click Run as administrator.

  3. Run this command after replacing <MyVM> with the name of your virtual machine:
