Cannot enable Windows Features (like .NET 3.5 and Subsystem for Linux) through PowerShell or Control Panel

I can’t enable Windows features through the Control Panel, features on demand, downloading them online, or through the Command Line or PowerShell. It fails with error code 0x80070002. I think it can’t find the files and I tried running a command to restore system files but after searching multiple sites I can’t fix it. I can provide any more information you need, I just need help activating these features. I have another computer which works fine so if I need to copy files over I can do that if you can tell me which ones. Thanks!

Edit: Thanks for the feedback . I will clarify some things. First, my Windows information is: Windows 10 Enterprise, Version 1803, OS build 17134.472. Next, I tried to turn both .NET 3.5 and Subsystem for Linux on through Windows Features and it still failed with error code 0x80070002. As for the command I ran, it was sfc /scannow

Its because those are not in the Control Panel. they're in Windows Features and the install has changed for WSL a bit.

Just hit the Windows key and type Windows Features to get to them.
