until ms solve this, i replaced my tabtip files with the older files from the windows.old directory. i've copied the following directories:
"C:\Windows.old\Program Files\Common Files\microsoft shared\ink"  to -> "C:\Program Files\Common Files\microsoft shared\ink"
and "C:\Windows.old\‏‏Program Files (x86)‎\Common Files\Microsoft Shared\Ink"  to ->  "C:\‏‏Program Files (x86)‎\Common Files\Microsoft Shared\Ink"

that brings back the older touch keyboard from build 1703 with the full keyboard layout for non-english region layouts.

i copied the directories using command prompt from windows 
recovery since the files are in use in normal windows boot.

I will try this later. Thanks!

Let us hope Microsoft doesn't maliciously block this workaround first chance they get.

I have same problem with Turkish keyboard.

... already initialization.. T_T

Reading everything, I found following solution:

- combination language NL and keyboard US (standard, not international) gives as result: 

• keyboard options working: Standard keyboard, little, position, pencil
• text suggestion working

- combination language with different keyboard (US International, RU, etc.) gives as result:

• keyboard options working: little, position, pencil. Not working (grey): Standard keyboard
• text suggestions working

When you want use the combination: a different language + keyboard not US standard + standard keyboard, you need copied the following directories using command prompt from windows:

• "C:\Windows.old\Program Files\Common Files\microsoft shared\ink"  to -> "C:\Program Files\Common Files\microsoft shared\ink"
• "C:\Windows.old\‏‏Program Files (x86)‎\Common Files\Microsoft Shared\Ink"  to ->  "C:\‏‏Program Files (x86)‎\Common Files\Microsoft Shared\Ink" 

Keyboard is changed by:

• settings touch keyboard>language>select language>options
• Control panel>Language

In general:

• touchscreen keyboard acts a little bit slower, but for me acceptable
• swiping does not work?
• Better solution? Setting is more easy, but the functionality is less. I hope that Microsoft will improve the touch keyboard in the future...

same here. the setting or icon simply isnt there. i only got 3 icons. and the setting to enable it in the keyboard settings is gone.

Is anybody from Microsoft looking at this issue? This is a real problem and needs fixing!

In the mean time how can people prevent Windows 10 Home from upgrading to 1709?

And I don't give the fix much hope. This isn't technical bug, it's mostly bad design. What was wrong with the old keyboard anyway?

How can I acquire these files as my .OLD directory has been cleaned out.

Cheers.
