Windows 10 update 1511 failed and no longer offered

If you have encountered this error:

You basically have two options:

1. Create an installation disk by using the Media Creation Tool.

2. The simple method would be to visit this website and click "Update Now".

3. You can also download the Version 1511 .ISO from the Download Windows 10 Disc Image (ISO File) website, create your own installation media, and install it that way. As of July 29th 2016, the only Windows 10 version .ISO that can be download is Version 1607

4. If you were using Windows 10 Enterprise the update can be downloaded from the Volume Licensing Service Center.

I have verified either option works. You can also wait a few days and a second check will automatically be performed. All of these options as of 11/30/2015 once again can be used.

For the purposes of an archive the 1511 Media Creation Tool is here.
