Some temporary files are constantly required by the system (irrespective of date they are created) and they cannot be deleted either manually or by any other software.

If you really want to delete those temp files, then you will have to boot into safe mode (https://support.microsoft.com/en-us/windows/start-your-pc-in-safe-mode-in-windows-10-92c27cff-db89-8644-1ce4-b3e5e56fe234)and then delete the files manually which will aid in successful deletion of those file. But note that, once you will again boot back in normal mode, chances are the temporary files will get recreated since they are needed by the system, background processes or any other application that you may or maynot run.

You cannot always clear 100% of your temp folder when you are boot up in the normal mode.
