Windows 10: Windows Update hosed .NET Framework, no way to repair it.

So, disregarding how idiotic the .NET installers are (not installing in any way like anything else from MS) the latest update to .NET framework - upon failure during installation, seems to have done the following.

(The reason it fails is that I have my %TEMP% folders set to a ramdrive. Everything else BUT .NET updates will work with this, but .NET Updates do something weird... When the %TEMP% folders are set to a normal folder, say C:\TEMP, the .NET installer will look for the disk with the biggest free size, and instead of using %TEMP% like everything else, will pick that disk and put it in the root folder with a cryptic foldername, like w:\7b77fff65737d83c41674cf3)



Anyway, what the shitty update from Microsoft did was:

1. Not set a restore point
2. Removed all traces of .NET from registry
3. Removed .NET 4.8 from the control panel / add remove windows features
4. Removed mscoree*.dll files from system32/syswow64
5. Probably a bunch of other malfeasance

To fix this, there is a bunch of tools available

• The .net repair tool from MS does nothing
• SFC does nothing
• Trying to manually install 4.8 from ndp48-devpack-enu, ndp48-x86-x64-allos-enu, ndp48-web does nothing, because they are blocked by a idiotic check that says "They are already installed" (probably a OS check, will try to look into this more).
• Trying to repair using the above installer packs does nothing.

In addition

• trying to launch powershell, which relies on .NET does not work.
• Trying to run the wushowhide.diagcab does not work because .NET isn't working (I had previously hid some updates, was going to look for them
• Trying to removing updates from the "Windows 10 Update" list only shows me the old control panel (which would've been good, except no .NET updates are listed there).

So guess like I have to manually recreate all the missing .NET information using procMon and another Windows 10 computer as 'template'.



What the f.



Or is there some other .NET repair tool that I do not know about?
