When you try to install the .NET Framework or IIS or other software and you suddenly got the error “Windows couldn’t complete the requested changes” – this article will show you what to do to fix it. This error has some accompanying error codes such as 0x800f081f, 0x800f0805, 0x80070422, 0x800f0922, 0x800f0906, etc. In majority of situations, this error message pops up when you try to install the .NET Framework which is required to run other programs or applications.
Why did you get this error?
You encounter this error when the related Group Policy setting is disabled. Take note that in the Home editions of Windows, the Group Policy is not available. To fix this problem, here are a few suggestions you could try.
Option #1 – Use the Group Policy Editor

Tap Win + R keys to launch Run.
Type in msc and tap Enter to open the Local Group Policy Editor. (Or you could also simply search for “Group Policy” in your Taskbar search box if you are using Windows 10).
Once you’ve pulled up the Local Group Policy Editor, go to the following path:

Computer Configuration > Administrative Templates > System

Once you have clicked on the System folder located on your left-hand side, double click on the Specify settings for optional component installation as well as the component repair setting located at the right side.
It should be set to “Not Configured” by default. You have to select “Enabled” and then click the Apply button.

After that, try to install the very same .NET Framework 3.5 on your PC. That should do it.

Option #2 – Try to use the DISM Tool
DISM also known as Deployment Image Servicing and Management, is a command-line tool that helps you in several cases. For instance, it helps you fix Windows Update system files that are corrupted, helps you repair Windows System Image in Windows 10, etc.
