Is your computer running slower and slower after upgrading to Windows 10? It is a symbol that your system partition is not enough to store the applications. Thus, you have to find a way to increase the system partition size for running Windows 10 at a normal or faster speed. If your system partition is running out of space, increasing partition size is necessary.
There are two ways for you to increase partition size for Windows 10. One is using Windows inbuilt program and the other is using a reliable third-party disk manager. I will show you one by one.

Step 1. Press “Windows+R”, type in “diskmgmt.msc” and hit ENTER.
Step 2. After that, you can see the main interface of Disk Management. Select the partition you want to increase and right-click, choose “Extend Volume”.
Note: Sometimes, you may encounter Extend Volume grayed out, that is because Extend Volume of Disk Management can only support to extend partition that has unallocated space neighbor to the partition on the right side. Some people may have questions. What if there is no unallocated space here or the unallocated space is on the left? Well, Disk Management cannot solve these problems. Therefore, you need to find another solution.
