About Windows XP 

Windows XP is delivered on October 25, 2001; the mainstream support for Windows XP finished on April 14, 2009, and the drawn out help finished on April 8, 2014. Despite the fact that Windows 11 has been delivered on October 5, 2021, and many individuals have overhauled OS to Windows 11, there are a few clients who are utilizing Windows XP. In Armenia, more than 60% of PCs are using Windows XP.

Windows XP  can't provide resize disk partition utility to resize partition, such as extend, shrink, move function, it can't help partition my hard disk into two or more to store other systems.  The built-in system of server 2003 has not resize partition function, and though Windows 7 or Server 2008 could bring about this aim, they can't meet disk partition requirements completely. For example, Windows Server 7 just could make the wish to shrink the half of disk come true; when there are two partitions in a disk, partition C and partition D, and spare space behind the D partition, it's unavailable to extend C partition to more capacity as you are unable to move D partition.  Then, it's time to resort to a useful and overall disk party utility. 

Here AOMEI Partition Assistant Standard is the one that I want to recommend. The tool can work under different Windows operating systems, ranging from Windows XP to the latest Windows 11. It is featured with many useful functions, including moving partition, resizing partition, merging partition, formating partition, and so on.  Free download it and check out how to use it to extend C drive in Windows XP/Vist/7/8/8.1/10/11.
