DualWin is a utility for creating a clone of the current windows(xp, vista, win7, etc). It can help you to create a clone of the whole windows (include Windows OS, office application, the favorite settings, etc) to annother partition, i.e.you will have two Windows on your computer separably .

You can use the Windows clone for a different purpose (such as entertainment, special transactions, or program testing, etc.), and your operation on the Windows clone will not affect the current Windows.You can also just use the clone as Windows backup(When the current Windows has problem running or is infected with viruses, you can switch to the clone and continue working and playing immediately).
