Users of Windows Vista are not that much now, especially when Windows 7 and Windows 10 released, some of the users may erase Windows Vista and directly install Windows 10, the newest version of Windows 10 is 1803. Fortunately, Data Wiper supports Vista System; you can run it or download Disk Partition Expert to Wipe Disk if the data in those partitions are less important.

The question put out by Shaon actually doesn't complicate, if you have Windows Vista in partition D, Windows 7 in Drive C, you can just use Data Wiper to "Wipe Volume" on the Vista Partition, then dooing a "Format Volume" operation to redistribute the space. What Shaon had done was common when Windows 7 first released, many people still have multiple boot systems in different volumes, if you would be a fan of a certain Windows System, and other volumes within systems might be wiped like this.
