I dd say a while back that windows 10 was best avoided. And one of my main reasons was that you have no control of updates.

The best you can do is to disable all updates in a the administrative options section.
Frankly this should be the default setting for ALL versions of windows. No updates, ever !

basically you need to do a system restore to before the update - make sure you are OFFLINE.
Then disable updates (look it up if you're not sure where they've hidden the administrative options section) and THEN reconnect the internet. Otherwise it'll just reinstall the same update.
