If you use VirtualBox and try to copy/clone a hard disk (VDI) file to use with another virtual machine, it will not let you add it because it complains that there is already an image with that UUID.
Fortunately the fix is simple – there is a hidden command available to generate a new UUID:
VBoxManage internalcommands setvdiuuid myfile.vdi
It always amazes me, in this day and age where so much is centred around money and people trying so many different things to make money, how much you can get for free. In particular i’m talking about software. For every piece of paid software, there will generally be one or more free alternatives. They are sometimes not as good, sometimes better – but free and generally someone – or a group of people have spent countless hours creating something…to give away for free. Excellent!
There is all kinds of different free software around – from web sites/online tools, operating systems to just plain old software.
Here is a very useful site i’ve found which is really useful for finding cool, free Windows applications: http://www.techsupportalert.com
