It’s so cool! It’s also very useful. You don’t need to be on the network when you do the updating. If you use Windows and get on a public network, you most certainly will get a virus before you even get fully updated! This software has saved me so much time! Almost like downloading a service pack and installing it, it pulls all of the Windows updates from Microsoft’s website and puts them into a big folder or iso for you so that you can just install an OS, pop in the cd that you made with this and just install all of the patches in one fell swoop. Awesome! … and FREE!
