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?

    Has made no difference. I get the following error when the 3rd line runs.

    1. creat .bak file, the content is:

    start /w pkgmgr /iu:Microsoft-Windows-NetFx3-OC-Package

    start /w pkgmgr /iu:Microsoft-Windows-NetFx4-US-OC-Package

    start /w pkgmgr /iu:Microsoft-Windows-NetFx3-WCF-OC-Package

    start /w pkgmgr /iu:Microsoft-Windows-NetFx4-WCF-US-OC-Package

    1. run as admin

    I don't know..., that's weird that you have all those extra features, something isn't right.

    Have you thought about using the "Reset this PC" option?

    Nope. It downloaded & installed from Windows Update. I only noticed when it told me the laptop required a reboot.

    No clue how or why that extra stuff is there. That all happened when I applied the CU & rebooted.

    Did you download the CU yourself?

    If so, could it be possible that you downloaded and installed the wrong CU? just asking...
