This is a screenshot of Puppy Linux, probably the fastest operating system i've ever used. It loads itself into ram and the applications run instantly.
It has all the stuff i need and i use it regularly at work for repairing computers, like backing up data, transfer files from a broken pc to a safe one over the local network, making partitions, test the hardware, etc. It runs great even on the oldest machines!
I'm really happy with Puppy and i suggest you to give it a try, it's worth it! [link]
