error code 0x80240438 while downloading .NET framework 3.5

As said in the title i am having a problem with downloading .NET framework 3.5. I have tried basically everything i can find online concerning the error code  ( even though all of the stuff i can find about the error code is about the store which i have zero problems with)

Error code 0x80240438

I had this problem as well on my machine at work. 
Try doing the following it worked and allowed me to download 
the .Net Framework 3.5 on my Windows 10 PC :  Go into RegEdit and 
set the HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU folder.  
DoubleClick on UseWUServer(UseWindowsUpdateServer) and change the value to 0.  
If the value is already 0 this fix may not work for you.  RESTART afterwards.


Moderator's note: It is recommended to create System Restore point before modifying registry.
