Sometimes, after you successfully install updates on Windows Embedded 8 Standard (WE8S) through Windows Embedded Developer Update (WEDU), WEDU does not indicate a successful installation. If you rescan for updates, WEDU shows that the updates have to be downloaded again. However, when you try to install the updates again, the installation fails.
This issue occurs when you try to install any previous WE8S Security Monthly Quality rollup update after you have already installed the latest WE8S Security Monthly Quality rollup update.
You can safely ignore these prompts. Because the WE8S Security Monthly Quality rollup updates are cumulative, you do not have to download and install previous Monthly Quality rollups after you install the latest update.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
