I try to install the anniversary update on my Windows 10 x64 operating system, but it fails with error code
0xa0000400
I already tried update with Media creation tool, and Windows 10 Upgrade Assistant but with no success. Current version of my operating system is 10586. Windows Update says that there my operating system is up to date.
Media creation tool:
I set back the language to English, restarted my machine, but I still received the same error.
Windows 10 Update Assistant:
I am the only one who is receiving this error? Someone know a solution?

The tool can be only used to download Windows 10 Home/Pro (N)/Singe Language Editions and not the Education.
Get the ISO via MSDNAA/Dreamspark or wait until you get the Update offered via Windows Update. Microsoft releases the updates in waves to make sure the servers are not hammered too much.
