Answer 1

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.

Answer 4

you can paste this into a admin powershell window and it should do everything you need without rebooting...

Set-ItemProperty -Path 'HKLM:\Software\Policies\Microsoft\Windows\WindowsUpdate\AU' -Name 'UseWUServer' -Value 0;

restart-service wuauserv;

dism /online /Enable-Feature /FeatureName:NetFx3;

Set-ItemProperty -Path 'HKLM:\Software\Policies\Microsoft\Windows\WindowsUpdate\AU' -Name 'UseWUServer' -Value 1
