Page files, previous Windows installation, temporary files, and other system files may have taken up the space of your system partition. Besides, you may have saved too many applications or large files to C drive that you are not aware of. Such as the default download folder is located in C drive.

Windows has many built-in programs, especially in Windows 10. You may never use some of them. Then you can uninstall the programs that you do not actually need. And you can also install the programs that won’t be needed in the future to free up space.
1. Click (right click in Windows 10) the Start button.

You can delete temporary files without running Disk Cleanup. The temporary files usually stored in “C:\Windows\Temp”, or “C:\Documents and Settings\username\Local Settings\Temp”. The files in both folders can be deleted directly.
Do following steps to delete Internet temporary files:

Recycle Bin, a temporary storage place, is used to store deleted files. To be specific, when you delete a file or folder on your PC, it doesn't get permanently deleted—it goes to the Recycle Bin. Therefore, you can free up space by tapping or clicking Empty Recycle Bin if you have files there. However, this way can only free up a bit of disk space for C drive since large files or folders won’t go to Recycle Bin.
