Windows 10: An app just appeared for no reason

I was in my Windows 10 PC,i was doing some pictures in the Paint app named win12 and win13.Later i put them in a folder,i reopened it,then there was a weird file named win12. I opened it but there was a blue error message, there was ,,Couldn't open this app in this OS." Later i realized, that it was an .exe file,so it got very suspicious. I started finding help, and i thought that it was a Windows 12's secret app. I think that isWindows 12's secret app still.

Mail app will not open on 10041.


Hello Adam,

This is the suggested solution below if you haven't already tried it.

In this Windows 10 build 10041, the Mail, Calendar, and People apps may be broken due to a licensing issue with the Store Beta. To get these apps working again, you need to follow these steps:

• Open powershell as administrator
• Run the command Get-appxprovisionedpackage –online | where-object {$_.packagename –like “*windowscommunicationsapps*”} | remove-appxprovisionedpackage –online
• Re-install Mail, People and Calendar from the Store (green tile)

 

Windows Updated(16299.309).KB4088776 Restart is required to complete.


Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.


And thanks for the tip of that program, I'll have it on my list.
