Hmm. interesting… Here is the english version:
Disable The NDU Registry
-
Open the Registry editor app again and navigate to HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Ndu.
-
Find and Right-click on the Start option and click on Modify.
-
Change the value from 2 to 4 and click on OK.

Restart Windows
NDU stands for Network Diagnostic Usage. It basically monitors the network data usage.
Why is it related to MSFS?
Because in MSFS Data settings, you can see that there’s a Data Consumption and Limitation feature. Somehow MSFS is using and connected to Windows’ NDU to monitor the data consumption. As you already know that MSFS is constantly downloading data from the cloud during flights.
Why disabling NDU may make MSFS smoother and more fluid?
Because most probably there’s a bug on Windows’ NDU (e.g. memory leak or process leak) which affects MSFS performance.
