Finally, after days of attempting to download this months batch, the final update got downloaded and installed on Sunday, on both computers. Since then, on the Windows 7 machine, another couple of "Important" updates refuse to download.
These are KB 3161664 KB316 1958 Security Updates for Windows 7 for x=64 based Systems for a total of 1.8MG. These were first presented Sunday morning with a Windows Defender definitions update, and non of it would load. Ran the definitions update separately and it downloaded and installed. But the two listed above are still being stubborn after many hours of "Downloading Updates"
Any suggestions about how to overcome these glitches.
