@all people looking to download via the media creation tool The XML that is used for downloading the esd has not been updated yet, so i guess you wait a couple of hours!
I just wanted the confirmation - whether the ISO available there is UPDATED or not and got my answer from @24q6hr that it is 10586. Because the same page is offering Update now on my windows 10 PC (Build 10586.494) saying "We noticed you are running Windows 10. If you would like to update to the latest version, click Update now."
I'm not aware of better one. If it depends on the Media Creation Tool binary, then it's obvious why I got this URL. Does the URL depends on Media Creation Tool version? (edit: answering myself: probably yes, the tool has it's own version which is the same as the build it downloads, sorry for being dumb ;-).
