When trying to update my Windows Server machines using the built-in Windows Update I had noticed that there was a single update that had erroring out time and time again. I finally decided that I should do something about it to resolve the problem so I began searching the internet and Microsoft’s site to see if there was a solution to the Windows Update error 80070490. Turns out, there was a problem with the Windows Update system installing the error. The quick and easy work-around was to download the update individually from Microsoft and install it singularly.

Here is the link to the download page (this is for the 64-bit version, if you have a 32-bit system, you’ll need to find and download the file for your 32-bit system):
Security Update for Windows Server 2008 x64 Edition (KB967723)
