Hi.

Had this before with a Windows 10 TH2 cumulative update in an earlier post I found conflicts with:

Cortana
Wireless - Marvell
Application Experience (engine)

I always keep these when removing to be safe.

Now it seems that KB3200970 in Windows RS1 fails to install in Windows Update because of some components removed with Winreducer 0.9.8.0.

So I will start with an earlier preset and lets see what they are this time...

---

Build v0.1

Status... Failed.
- Windows Update... Fails.
- Error message after restart.
- Post Setup - Windows Defender Update... Works.

Build v0.8

Status... Failed.
- Windows Update... Fails.
- Error message before restart.
- Post Setup - Windows Defender Update... Fails.

Build v0.9

Status... Stopped.
- Added Accessoiries.
- Added Services.

- Added Features - Accessories - Media Player.
- Added Remover - Accessories - Action Center.
- Added Remover - Accessories - Anytime Upgrade.
- Added Remover - Accessories - ELS.

- Added Remover - Disk Quota.
- Added Remover - Previous Versions.

Build WU v0.8

Status... Fails.
- Back to Preset v0.3.
- Removed Remover - Spell Checking.
- Removed Remover - Text Prediction.
Conclusion: Tried various combinations from where it worked. Adding or removing did not make any difference at all. Very strange. Still looks like all those are interfering with Windows Update.

Build WU v0.9

Status... Fails.
- Still using Preset v0.3.
- Removed Remover - Drivers.
- Removed Remover - Languages.

Final Conclusion: Now I understand. Something is going wrong with the integration of the Servicing Stack Update needed for upgrading. When Windows Update installs the Servicing Stack the cumulative updates are working fine. When they are integrated by Winreducer the cumulative update fails every time.

Will try some last presets without integration and will see if there are any error messages.

- Update KB3199986 (Servicing Stack)
- Cumulative Update KB3197954 (10/27/16)

Confirmed that my unmodified RS1 works fine. Still can not find what happens. Looks more and more that the cumulative update always breaks on a winreduced install. There are two possibilities. First the cumulative update fails on updating missing files. Or second it halts when it detects that a windows install is modified in any way.

That's all folks. My bad I did not notice it earlier. Without integration and a Windows Update everything went fine.

So consider this thread closed.

Bye bye.

Thanks.
