So I use Parallels Desktop 5 to run a very slim version of Windows XP. I use to play some games but not anymore. The only thing I use Windows for now is to run Microsoft Word 10, certian templates I use demand macros that only work with the Windows version. With this being the case I was wondering what general steps I should take in order to maintain my virtual machine. Do I need to defrag or disc clean every so often. I have heard people complain of VMs causing their harddrive to crash just because they installed it and occasionall use it but never do anything else other then run it every once in a while. Also I was just curious how running a windows program like "disc cleaner" or how defragging your harddrive on a VM work. Anyways, thank you in advance.
