Why Need to Extend System Boot Partition?

As applications continue to be installed into the Windows system, one day, suddenly you will find that the system and/or boot partition do not have enough free disk space, and when every time the system starts, Windows always prompts the following information:

You are running out of disk space on SYSTEM (C:), To free space on this drive by deleting old or unnecessary files, click here…

Low Disk Space

In this case we have to delete the unwanted files for getting more free space and ensuring Windows normal operations, however, deleting files is not the best way. If my system disk has a total of 931.32GB - the system boot partition (C: drive) is only 51.86GB and 834.84GB was allocated to data partition  E:. It is clear that E: partition space is large enough, and now the best solution is to allocate 100GB (even more) from the E: to C: by extending system partition. You can permanently solve the problem by using the Extend Partition Wizard of AOMEI Partition Assistant which is considered as a helpful Windows partition manager. Here is the partition layout of my system disk before extending system volume as shown below:
