How to Get Rid of My Phone on Windows 10
In Windows 10 you may have uninstalled the 100% of no use to most of us app "Your Phone". Personally I don't ever want to text from my windows 10 device or use an app on my phone on my PC. I literally so no point to it wasting resources. You may have noticed it's back after you removed it. Well that's thanks to an update where they once again forced you to have crap you don't want or need. So do this to remove it:
Right click the start menu
Click Windows PowerShell (Admin)
Coy this command Get-AppxPackage Microsoft.YourPhone -AllUsers | Remove-AppxPackage
Paste it when the command line prompt arrears and hit return then wait for it to be removed.
Reset the computer and it should be out of your life.
