Windows Update will give you the following error: "Windows Update cannot currently check for updates, because the service is not running". You will also get a .NET error "HRESULT 0xc8000247" if you are trying to install and it will fail.
To Resolve: Edit
1. Run - services.msc - Windows Update Service and Base Filtering Engine services need to be running.
2. If they are, and you still get the error, go here (http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02219204&cc=nl&lc=en&dlc=en&product). Follow the link to install the Intel Rapid Storage Technology Driver. Note: You don't have to have an HP machine for this to work.
