Error 0x800f0954 when installing dot net on Windows 10

You may receive this error when trying to install DotNet (.net) on Windows 10 and you are using a WSUS server. This error may occur of the .net installer is not approved in WSUS.
As a temporary workaround, change the registry key “UseWUServer” to 0. It is located at:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
After the registry change, restart the Windows Update service. You should be able to install .net at this time. Once done you should change this key back to its original value (or wait and allow Group Policy to do it for you.)


Any way, the problem in my case has been solved.

There is an new error in the installation.

It is shown that, Could not find the following module: 'dredgesim'

I use the attached configs files, but it is still failed.


The error is as follows.
