used from a read-only medium like a CD or DVD. Using it by default does not create any permanent changes on your computer. You can change user settings and install additional programs from within the live it and try it out. There are a few limitations in using a live system. The first is that as all changes you do within the live system must be held in your computer’s RAM, this only works on systems with Manager in Windows. Partitioning tools always provide a way to show existing partitions without making changes. 在一般情況下，改動一個已經建立檔案系統的分割區，會導致其中的資料遭到損毀。因而，您每次都 應當在重新分割之前先做好備份。繼續拿房幾作比喻，在移動牆壁時，您最好在把擋路的傢俱都移開，否 則就要冒著傢俱被破壞的危險。
