If you're running it from your hard drive, on a Windows system, you can recover some space on your hard drive by deleting folders related to Mac, and Linux.
Also, be sure to properly exit from the session, rather than just closing the window. If you don't, it will leave the Apache web server application running in the background on your system, which will use valuable resources. Apache has a little red icon that will be in the lower right corner of your screen when it's active. You can also see it in the Windows Task Manager.
