Twain scanning no longer working

Has anyone else run into a Twain scanning issue lately? Scanning was working fine last week and now the Twain driver never shows up as an option. This involves several users with different printer/scanners installed. It just doesn't work anymore. One thing that has changed was Microsoft's latest 'Cumulative' update to Windows 10. That pushed out last week and is installed on all of the Twain users PCs. I guess I'm just hoping for a fix!

Thanks!
