As you can see neither seem to be very accurate, but the gest seems to be that you have lost some available free space on your hard drive. Presumably as a result of the upgrade.
First be advised, be careful as to what you clean and how you clean it.
There may be a couple folders on your drive that are accounting for much of your additional consumed usage, Windows.OLD as well as $Windows.~BT, and $Windows.~WS.
These folders or at least two of them are required to support your ability to revert back to your previous Operating System should you desire to do so.
You have a month to do that if you need to and I believe that after that time, Windows 10 will magically make at least two of them disappear. You may want to wait until you are certain that you are happy with the results of the upgrade before then.
