    Windows 10 Pro used 46GB


    It was installed at Aug, 2016 on a new partition (not upgraded from an old Windows). Only 32 programs are installed and 10 of them are drivers. The biggest program is NVIDIV graphic driver (600MB). On C drive, the total number of files which are bigger than 100MB is 22

    My personal files are saved on another partition. Does Windows 10 Pro need 46GB? If not, how to release the space?

    In your first screenshot you are showing, at a guess, about 8 GB. In the disk cleanup file you have to check the boxes for them to add to the total cleanup. You can also click on clean up system files to get more.

    Please just open your C drive and show us the contents of C. Under the view tab at the top make sure the size option is checked under columns, if it isn't already. Also, please show us a screenshot of Disk Management. This will tell you how.

    To answer your question, no Windows 10 does not use that much space, but depending on what is installed, you can use that much.

    That's not C: drive on your picture, click on it to show. Also turn off hiding of System and Hidden files/folders. In Disk cleanup click on "Cleanup system files", there should be more options.
    For more detailed look at your drive(s), try a program like this: DiskSavvy - Disk Space Analyzer
