Cant upload picture, error [solved]

Hello!

I am running Drupal8 on localhost. I have set it up correctly.

So when i create new content type (for uploading picture in frontpage etc), and then adding content (Upload Picuture-Browse) and clikcing Save and Publish, then i get an error:

The file php93C0.tmp could not be saved. An unknown error has occurred.
File upload error. Could not move uploaded file.

Error report details:
Message Upload error. Could not move uploaded file 2.png to destination public://2017-07/2.png.

What i am doing wrong?
Permissions should be okay? :D
Temporary Direcotry: sites/default/files/tmp

Got the answer myself: I looked from http://localhost/admin/reports/status/php
upload_tmp_dir location,and i noticed that C:\Windows\Temp. So i gave full access to windows temp folder and now i can upload picture!!
