Hello, as I've said before.
In order to have Windows with the most updated version that allows you to use the right click on the search bar (1903 - 18362.535) you must do the following:
1 - Install EVERYTHING, including the 1909 version and all its updates.
2 - Go to the windows program uninstaller.
3 - (On the left side) Select to view installed updates, the window will become uninstall an update.
4 - Select and uninstall the following update: feature update to windows 10 version 1909 via enablement package (KB4517245)
(Uninstall only this update)
Note: I've installed the 18363.535 (1909) and the right click is still disabled, the latest version with the right click in the search box avaliable is the 18362.535 (1903). I'm starting to think this wasn't a bug, but an elemination of an extremely useful
feature...
I really hope that Microsoft implement again the functionality that was removed, not having it makes my job a lot harder.
Apparently Microsoft is doing the same thing it did when it removed the Windows 8 start button, eleminating Windows features that users need...
I hope I was able to help.
