Well Google says the error code means MS has a problem with your Windows Certificate - NO WORRIES - I've had this problem a few times.I have two PCs here and both are getting stuck doing Windows update, one finally gives message 0x800705b4 and the other just sits. Both are running Windows 10 Version 1607 build 14393.447
Is this a general problem or just me?

Here's a neat trick! Click on this link. If you have the latest W10 update, you will get this message "Thank you for updating to the latest version of W10":smile:
