Windows 10 (2004) Problem removing keyboard layout

A problem that appears in Windows is the inability to remove a keyboard layout (hereafter keyboard layout). If you do search of the title online, you'll see that it appears as a problem more often with Windows 10 than with older versions.

Our example:

The language taskbar shows 3 available languages: Greek, English (US) and English (Philippine) added by mistake.
Now in the Windows 10 2004 version in the Control Panel the Language section has been removed and replaced with a selection in the path
Settings Ώ Time and language → Language. Keyboard.

Following the above path to remove the last layout, we see that it is not in the list

Using Powershell and the command WinUserLanguageList to show us the installed keyboard layouts of the system, the results returned were only the Greek and English layout.

In the language switch with Alt + Shift, Filipino English is a real order!

On the internet, the solutions that exist either follow the process of removing the Keyboard layout via the Control Panel (for old versions) or from Settings, or check the Region option, or recommend the deletion registry keys like his

HKCU \ Keyboard Layout \ Preload \

In our case they don't application because our system does not see the provision we want to delete.

The solution (with its explanation):

We write in the Start menu: regedit and select Run with administrator rights (Run as Administrator).
Go to the key (or copy - paste in the address bar)

HKEY_CURRENT_USER \ Keyboard Layout \ Substitutes

Each string (reference string value) is a reference to a language and the value it takes is the keyboard layout.
The string (Default) has no value and refers to the default system language (Settings) Area)

The string 00000409 is the EN-US language code that is usually second to all
facilities. In our case making a double click above it, we see its value is 00020409, that is, the language layout is US International (QWERTY).

There is also a second string 00003409 with price 00000409 which with an internet search is PHI-US (Filipino English) with US layout

So:

Delete any string other than (Default) and 00000409
If the value in the string 00000409 is a code that we do not have the opportunity to specify, as a sure solution is to enter the same code 00000409 as a value and then (if necessary) change it in the path:

Settings και Time & Language → Language → Keyboard → English → Options → + Add Keyboard

How the problem can be caused:

Personal assessment is a bug caused by the (albeit temporary) change of Area (option
another country). It is the only process by which the language keyboard of the country we have chosen is added without our own other action. By changing the country to the original, this keyboard remains and we can remove it from the Keyboard list.

However, when the keyboard layout is identical to an existing keyboard (in our case Filipino English had the same layout as the US English string), then this is not removed.

This article is not a translation of another and the estimate for the cause of Bug does not exist as explanation on the internet.

So if any reader has another opinion let them share it.
