As the latest operating system, Windows 7 becomes more and more popular all over the world. Compare with windows XP/Vista, Windows 7 has added so many new option interfaces and it requires much more space than XP, Therefore, after upgrading to Windows 7 from XP, you may face the low disk space problem which is a high risk to our computer. This is the reason why we need a Windows 7 partition manager to resize partition.
Like other operating system, Windows 7 has a built-in Disk Management also. Unfortunately, compare to Windows XP there is a little improvement. Resizing partition seems more easily than before. However, in fact, extend system partition is still a hard task. Users can not extend partition freely; sometime you may find the "Extend Volume grayed out". Only the unallocated space is close behind the partition then the feature is active.
Because of the shortage of the built-in Windows 7 partition manager, we need to find other partition manager which is more professional than Disk Management. Such as Partition Magic, however, as we know Partition Magic doesn't work for Windows 7.
Luckily, as one of the partition magic alternatives, Aomei Partition Assistant is being regarded as the latest "partition magic for windows 7" by more and more users.
