Over time, it is unavoidable that there is not enough space in the Windows 10 system partition.

The end result is that the system is getting slower and slower, it will seriously affect your productivity. I'm sure many of us have encountered such a problem and many people have opted to buy a large disk and reinstall the entire operating system and applications.
