We offer links to download all wallpapers of Windows 10 that will come with the final version and also with the Technical Preview version.
In about three weeks the Windows 10 will reach all users, but if you want to enjoy the wallpapers before that, you can download them directly from the web. There are 12 wallpapers from Windows 10 available and all are in a resolution of 1980×1200, although the famous full light blue logo which will be assigned by default has a 4K resolution.
If you installed the Technical Preview version, you can access them through the path C: \ Windows \ Web. In that folder, you can also find the lock screen. If you are in a build version, you will only get them with the final version, and if you liked none of these and preferred the early Technical Preview version (much nicer in my opinion), I have gathered them all and you can also download them from one drive .
