Sometimes it is necessary to manually remove an app using the powershell

here is how to do this

In order to remove an app package you need to have the full package name

you can use the get-appxpackage command to get the full name

for example if your app package has the name MyApp in it enter

get-appxpackage -name *MyApp*

you will get all the information on your app package. look for the line that says: PackageFullName

then enter

remove-appxpackage fullNameOfPackageHere -confirm
