Windows 10: Unrecoverable playback error: Class not registered (0x80040154).

I had problems with a Realtek audio driver so uninstalled and pared back to the Win10 MSoft generic driver. I then installed the latest Realtek driver from the Microsoft Update Catalog (MUC). All working, no problems, sounds good. I then installed the latest Realtek driver from Mokichu ASUS support site (this a later version , 8945, than the MUC). With this driver, which includes additional components from A-Volute/Nahimic, I get no sound from any source and Foobar gives a message... "unrecoverable playback error: Class not registered (0x80040154)". Either this driver pack comes complete with a problem or the uninstall (back to the Win10 MSoft generic driver) has resulted in a Registry problem. Any guidance on how to identify the "class" which is not registered would be greatly appreciated.

Class not registered. Ще съм Ви благодарен, ако можете да окажете съдействие за решаване на проблема. Поздрави: Генади

Hello, I guess I accidentally deleted a system file or directory. Now, when I try to run a program installed on my computer, "EPLAN" displays the following message: Connection to 'EPLAN Client Service' not available. Error [0x80040154]: Class not registered.
I would be grateful if you can help solve the problem. Greetings: Genadi

0x80040154: Class not registered when edit data

When I try to edit data files (like changing the rating of an MP3), I get a 0x80040154: Class not registered error. I am using Windows 10 Education N. I get this error since the Windows update, which changed the appearance of the Windows login screen.

You can also see, that there is no further information about the mp3 displayed.
