KB2919355 is the bulletin number attached to Windows 8.1 Update 1. Last week, the update was offered early to MSDN and TechNet subscribers as part of Build 2014 release goodies. Many took advantage of the timely bits and installed the update early.
Today, many are reporting that KB2919355 is being reoffered to those with the update already installed from MSDN or TechNet. Apparently, the update coming from Windows Update is not recognizing that the bits already exist on the PCs and devices.
The issue was identified early by Microsoft, around 11:30am Redmond time, and the problem was supposedly fixed.
I promise more updates as the story evolves.
UPDATE: Apparently, the KB2919355 release today, April 8, 2014, includes an update not included with the MSDN/TechNet update available early. Today's release has a new file included (KB2934018) not available with the MSDN/TechNet version. There's two fixes. Choose your favorite:
- Just go ahead and install the KB2919355 offered today. It will make the necessary changes to the MSDN/TechNet version and stop reoffering.
- If you alreayd have the MSDN/TechNet version installed, just download KB2934018 manually and install it. You can obtain this update from here: http://www.microsoft.com/en-us/download/details.aspx?id=42335
