Can't enable .NET Environment in Windows 10 1903

Well, this is a showstopper for me. I'm in the Release Preview ring & installed 1903 (18362.30) yesterday . Update went fine. No issues experienced.

Got a Cumulative Update to install today (KB4495666). Installed it & rebooted. Build is now at 18362.53. .NET framework was disabled & 90% of my applications will no longer run! In "Control Panel/Programs and Features/Turn Windows Features on or off", ".NET Environment" is unchecked. If I check it & hit "OK" it take about 10 seconds & says "Windows completed the requested changes". The .NET Environment, however, is still unchecked when I go back to "Turn Windows Features on or off" & >NET applications still don't work.

I've uninstalled all of the updates installed today (KB4495666 & KB4493478), but .NET is still utterly broken. I've read that this was an issue prior to the release of 18362 to the Release Preview ring but was supposed to have been fixed. Looks like this MAJOR bug was reintroduced with the cumulative update?

    Thank you,

    The DISM command is uneffective, so the only solution is tu go to the insider thing.

    and will have to format/ reinstall Windows and all the stuff when the update will be published and available for the public.

    I'm completely stunt that Microsoft doesn't reac, I mean, they released an update that breaks the .NET infrastructue for ALL the Win10 users, and they want all the Win10 users to jump to Beta testers ?!?! that is such a non sense.

    When I've installed the Windows, it was working, it is due to an update, this should be fixable, right ?

    Not what you want to hear but CU KB4495666 did not break it "for ALL the Win10 users"

    It didn't break mine and I don't know what it is, but there must be something else involved.

    I tried installing build 18362.30 and recreated the .NET issue. I let it upgrade to the latest CU, but .NET remained broken.

    I then upgraded to 18912, using the ISO. That fixed .NET. Once I confirmed that .NET was there and I had PowerShell working, etc., I rolled back to 18362.175. However, .NET was again broken.

    So, if the only way to fix .NET is to upgrade to 18912, you may have to keep running that until Spring 2020.

    However, for most, a clean install of Windows 10 version 1903 will auto-update during install to build 18362.175 and .NET will work properly.  If a clean install is an option, I would try that instead of using the Insider builds.

    Just wanted to straighten that out as there seemed some confusion on that point.

    I'm not confused but someone else is, so why are you replying to me?
