@Russ Sorry for the waiting. I've tried this and it finally works well. Thank you so much.

ASH: Yes, I check that the changes are done in this. I have tried changing things but that did not work. I also tried using the Alexa app. Same situation. I must say that the updates appear at least about 1 min later. For some reason, sometimes they take more time.

BGC: I restarted it but still does not work...

I really want to be able to run background commands. I checked that TRIGGERcmdAgent is listed. Today, it suddenly showed both the reboot command and another one for shutdown I made yesterday. But, after changing the trigger for shutdown, the reboot one vanished from web and from device in Amazon Alexa app. About 15 min later, it was detected again and appeared doubled in web.
In the case of the skill, I tried saying that for both calculator and notepad. Also changed the name of calculator in case Alexa (configured in spanish) was not understanding it. In the Runs list for any of my commands I just found these two: "Command ran" and "Trigger sent from website".

Hi, there. I'm having some problems with TriggerCMD working in spanish. First of all, I've just installed it and checked that there is the deffault reboot command in computer Command Editor, but there is not in web. I've read that installing Background Service should do the work, but I clicked that option and authorised it several times achieving the same result, nothing. Actually, I am not sure if it is installed.
The second problem is the following. I checked that the commands in foreground work calling them from both the web and the Command Editor option. But the computer does not run them when asking Alexa. I've tried the deffault commands and the routine way (just thinking that the request sequence might be the wrong one). Alexa confirmed that Smart Home TriggerCMD was activated and identifies the devices (calculator and notepad are detected and active during these tests). When it say the request, Alexa's response is like it actually sends the command, but as I said the computer does nothing. I also tried to start everything again, meaning that I tried to reinstall it in my computer, reactivating the skill, delecting my computer from Computer list, turning off Avast... I do not know what else could I try.
Thanks for your help.
