Notification: "We need your help to finish adding a feature"

I keep getting this notification:
"We need your help to finish adding a feature."

When I click it, it opens the "Manage optional features" settings page with a list of 8 features under the "Add a feature" button. The listed features are mostly English(GB) things, but Internet Explorer and Windows Media Player are also listed.

Clicking on any of the English(GB) items, e.g. "English(GB) handwriting" brings up a "Manage" button. Clicking the Manage button opens the "Region & Language" settings page, but no clue as to what it wants me to do next.

Clicking on "Internet Explorer 11" or "Windows Media Player" brings up an Uninstall button.

Nowhere is there any clue why the notification has been displayed or what I am supposed to do to get rid of it. Does anyone have any ideas why this notification is appearing?

Hi dalchina, here are the screenshots:

I see the cumulative update KB4054517 done at least a few days ago says it needs a restart, which it has had more than one of, as it has at least one restart every day. Maybe this is significant?

In "Manage Optional Features", I tried clicking Uninstall for Internet Explorer and for Windows Media Player, but nothing seemed to happen - they certainly did not uninstall.

The problem only started a few days ago and I have been googling it for a few days but found nothing relevant.

I have not changed any language settings recently, but I do have Spanish keyboard installed as well as UK keyboard.

I have no system restore points.

chkdsk and sfc both completed without errors.

One of the HDDs in my system is dodgy, (it has had end to end errors for a long time, but doesn't seem to get any worse), but it is not in use and is not mapped to a drive letter in Windows. Now I am getting notifications from Hard Disk Sentinel predicting failure of my rubbish HDD - I suppose I should remove it and put it in the fire.

Hi, thanks for your comments. There is a clue in the actual notification. I hadn't spotted that the symbol is clearly a language thing as it is the same symbol seen in Manage Optional Features with all the English(GB) items.

Will try uninstalling the update later and see if it fixes this.

Cortana does not work at all because I have it turned off. Like I did with the old paperclip helper. I also have all the games uninstalled, although this time they seem to have come back again - not really a big deal, but I don't play games on my desktop PC. I do a daily backup of files that I need, but do not often save images of the OS and apps any more. I do use Macrium Reflect after a clean install, but generally the OS has moved on by the time I need these, so I just do another clean install from the latest iso. I run Windows Defender and do a scan with Malwarebytes whenever anything suspicious happens. Pretty paranoid really and have most (maybe all) privacy options turned off.

Here is my Settings | Region & Language page:

For Spanish, it says Language Pack available, and clicking on it gives ma an Options button.
Clicking the Options button, opens another page:

This is a bit strange, because it says it is downloading "Basic typing" (I will have to look up what that is), but nothing is happening on the network (according to Netmeter), so it isn't actually downloading anything. Now, clicking "View progress" dumps me back into the "Manage optional features" page, which is disappointing as I have seen that before.

I shall try removing Spanish as I don't need it today and see what happens. I only need the keyboard anyway. Oh, I clicked "Remove" and it went, instantly, without seeming to do anything. except delete the icon off the notification bar. I'll give it 24 hours before trying to reinstall the Spanish keyboard - let's hope it hasn't gone forever.

This is frustrating, but not the end of the world!

When the Spanish language pack is uninstalled, there are no warnings.

When I try to install the Spanish keyboard, it seems I now have to install a complete 'language pack', which will not install properly and results in these persistent warnings. It used to be a simple matter to install alternative keyboards, but something has changed...

When I look at 'Manage Optional Features', there are no Spanish items listed, just the English ones.

When I look at 'See optional feature history', it is really odd, with lots of recurring entries. The latest batch of installs seem to have all succeeded, but look at the date: '01/01/1601'. Right in the middle of the Spanish Inquisition if I remember correctly - let's hope it has nothing to do with that.

Strangely, the only 2 entries with the correct date are the installations that are reported as failed. The list carries on beyond that with lots more entries with the date '01/01/1601', including the uninstalls of Internet Explorer 11 and Media Player which I did a few days ago.

Despite everything apparently installing, I still get the warning notifications. But at least the Spanish keyboard works, which is the main thing.

Downloaded the language pack as you suggested. Uninstalled it first, and then re-installed using the cab file. Still get the notification and it still thinks it was done hundreds of years ago.
