Hi, Windows Live Security Essentials cannot be installed in Windows Server 2008 R2, but you can install it in Windows 7. In addition, you can run Hyper-V in Windows Server 2008 R2, but you cannot run Hyper-V in Windows 7. You still can run other virtual machines in Windows 7 with Windows Virtual PC. If the above suggestions cannot fix the issue for you, please try to reset Windows Update components and run System Update Readiness Tool to repair the system files. For the detailed steps, please refer to the following Microsoft articles: How do I reset Windows Update components? http://support.microsoft.com/kb/971058 Description of the System Update Readiness Tool for Windows Vista, for Windows Server 2008, for Windows 7, and for Windows Server 2008 R2 http://support.microsoft.com/kb/947821 Advanced guidelines for diagnosing and fixing servicing corruption http://technet.microsoft.com/en-us/library/ee619779(WS.10).aspx Regards, Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

Hi g_stuff_99, Do you use WSUS or no? What update is it installing while you get this error? Always the same or no?

hi, When I boot into Windows Server 2008 r2 the automatic updates fail and I get an error 80070005. , yours truly g_stuff_99

hi, I was just looking over the entries in the Application tab of the Event Viewer and I noticed that one of the errors mentioned Security Essentials was not installed; so, a better question would be is there a free anti-virus product that is compatible with Server 2008 r2 or is there a way to run Windows 7 and still be able to create VMs in Hyper-V? , g_stuff_99

Hello, the error id belongs to Access denied so make sure to use RUNAS Administrator when starting windows update.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
