.Net Framework 3.5 fails to install with error code 0x800F081F

Original Title: Error installing .net framework 3.5 sp1

I did a refresh of my install of windows 8 pro (64 bit), because Weather and several other apps were failing (they started, then the main window closed, but the small window stayed in the task list to the left; event viewer gave access permissions errors).

This seemed to sort most of the apps BUT now I cannot re-install many programs as they need .net framework 3.5 and this fails to install with error 0x800F081F. I even tried downloading the full installer and running locally but it still gives the same error!

I need the framework to work with OpenXML development, a large part of my work.

(I should also point out the refresh says most apps are retained - it fails to mention all applications are removed!)

I have Win 10. After a half dozen tries to update over the last month, and the PC freezing every time, then it restores old version of 10. I have run the update troubleshooter 3 times. I have run MSRT. I have run Command Prompt. I have finally located Error: 0x800f081f.

I'm not an IT person. What's next? What's the easiest (simple) way to fix this?

Every time this happens to me, its because Group Policy is looking for a WSUS server that may be preventing you from downloading the .NET patch directly.

I've had the exact same thing happen, and as long as you have permissions to do so, follow the steps below and it fixes it.

If you are also facing problems while installing .NET Framework 3.5 in Windows 8 or later, check out following method to fix the issue:
1. Type gpedit.msc in RUN or Start search box and press Enter. It'll open Group Policy Editor.
2. Now go to:
Computer Configuration -> Administrative Templates -> System
1. In right-side pane, look for "Specify settings for optional component installation and component repair" option.
2. The option would be set to Not Configured. Double-click on it, set it to Enabled and enable "Contact Windows Update directly to download repair content instead of Windows Server Update Services (WSUS)" option.
That's it. Now try to install .NET Framework 3.5 again using Control Panel -> Programs and Features or by using DISM command and now you'll not face any problem.
