Since many days I am facing problem with installing KB958559 in Win 7 RTM. I getting event log, "Installation Failure: Windows failed to install the following update with error 0x80070005: Update for Windows (KB958559)." I am unable to go C:\ProgramData\Microsoft\Windows\Start Menu\Programs, I am the administrator, although then I don't have permissions to access the folder. Why it is happening ??
