Windows 10: error message while installing .NET Frameworks 3.5

I am running Windows 10 Enterprise 22H2. Every time I login to this machine I get a message that I need to install .NET Frameworks 3.5. After going ahead with the install process, I get an error message stating "The changes couldn't be completed. Please reboot your computer and try again. Error code: 0x800F0954".

Unable to download any framework for .net - (error code 0x80070002)

OK, the Windows 10 Feature installation method should have been straightforward, but since that errored out as well, something else seems to be going on with your Windows, so wait for somebody with more experience to suggest a way out.

In the mean time, if you haven't already, you could give muchomurka's suggestion a go as well with the elevated prompt and an install media to see if it works. The following link shows the detailed steps involved.

Hi,

Welcome to Microsoft Community and thank you for your interest in Windows 10.

I suggest you to follow the below steps to check whether the .NET Framework 3.5 has been installed or not.

• Press Windows+X and then select programs and features.
• On the left hand side click on the option “turn windows features on or off”.
• Check whether the “.NET Framework 3.5” has been checked or not.
• If not check then I suggest you to check it and then install it.

Hope this information was helpful and do let us know if you need further assistance. We will be glad to assist.

If you have windows 10 installation media (DVD, ISO, USB) attach it. Run cmd as admin and run:

Where E:\ is the drive letter assigned to installation media. If you still get error, you have to uninstall every update to NetFx4.5, then repeat steps above, and again update NetFx4.5 as stated here. Also check out here if you're joined to domain.
