Cant install updates

I am trying to install updates to 1607 but get the error message "We are unable to install the updates"
and quote error number Ox800705b4,any idea what this means?

Ox800705b4 is apparently a timeout error. Several things you can try...

1. Stop and restart the update service an background intelligent transfer service. In an elevated command prompt type the following commands:

net stop wuauserv
net stop bits
net start wuauserv
net start bits

Or you could just reboot by clicking Start and selecting Restart on the power button. Either way, then re-try checking for updates.

2. Turn off 'Give me updates for other Microsoft products when I update Windows' in Settings > Update & security > Windows update > Advanced settings. Now try checking for updates.

3. Run the Windows Update Troubleshooter.
