Win 10 Home on a Lenovo Laptop G770. The other updates install, but this one has always failed. One message a month or so ago I thought said something about Microsoft was working on a solution. I think it has been over month with this failure to install. How do I know if this is something I need to attend to or just forget it? Today the Windows Defender virus definations installed and a Adobe Flash update installed, but this one failed again. Thanks in advance for suggestions.
