Custom hotkeys to change input language disappear frequently

I have repeatedly tried to set hot keys for: English, German, French, Mandarin.  All disappear, except for Mandarin - this agrees with several of the other replies, in that only IMEs seem to be able to keep their hot keys.  The choice of hot key has no effect.

I also have this problem:

1.I set language bar hot keys including Mandarin

2.They work

3.Then I press WIN-L lock screen

4.When I log in again, keboard shortcuts disappear

Microsoft, I've paid for your product including this feature.

I know, that you in Seattle use mostly English only, but still, there are people using many different languages on your software. Like we in this forum.

The WIN-SPACE combination is awkward, because you have to press it, then decide how many more to press and then press X times again. UX of this is bad.

So when do you fix it?

I have exactly the same problem...

The language shortcuts worked perfectly on my old computer, with an older version of Windows. Since my update I need to put in the shortcuts around once-twice a day. Some of them are always retained, but most of them disappear. I use 11 languages on my computer, so it's a real pain!

I have contacted Microsoft, as well as Lenovo, on this issue, and the replies have been pathetic: they seem totally clueless, and I seem to understand the problem better than they do. After around 10 calls I still get suggestions like "reboot the computer", by which stage I am about to pull my hair out.

I have decided that - unless this gets resolved very soon - I will never buy Microsoft again. The combination of total cluelessness, lack of professionality and - worse - complete disinterest is a bit too much. I now spend around 15-20 minutes a day resetting my shortcuts, EVERY DAY. I hadn't made the shift to Apple yet because I was too lazy to learn how to use a new operating system, but I will now definitely and definitively switch: I am not taking the chance that this will happen again on my next computer; and from what I understand, the chances are high it will indeed happen again.

I am very frustrated and disappointed with Microsoft, particularly with the (lack of) service.

If anybody has any suggestions how to resolve this in the meanwhile, please let me know.

Thank you

Exactly the same problem here.   Using a Dell XPS 2027 all-in-one.   I didn't notice the problem at first, but had to refresh my system and reinstall everything from scratch.   Since then the hot keys keep disappearing - sometimes a couple of them, other times all of them go.   Lots of people seem to be having the same difficulty and have done for some time (I upgraded from XP and it works fine, as does Windows 7 on my work laptop), so my question is has anyone found a solution yet that works?   Like the guys from Microsoft?   Don't see many useful postings here from them.
