In Windows 10 releases, lots of apps are pre-installed. Different than in Windows 8/8.1, most of these apps cannot be uninstalled by GUI.
If you want to remove them, you still can do that by using powershell.
1 Start powershell with administrator privilege.
2 Enter these 2 commands to prepare the workspace.
3 Enter this command to show all installed package.
Get-AppxPackage -AllUser | Where PublisherId -eq 8wekyb3d8bbwe | Format-List -Property PackageFullName,PackageUserInformation
You will see some apps listed. The packages with status Installed are ready for your further removal.
4 Use this command to remove one app.
Remove-AppxPackage -Package packagefullname
The packagefullname is the text listed by step 3. Usually, it starts with Microsoft and end with 8wekyb3d8bbwe.
You need to repeat the step 4 for each app you want to remove.
Not all apps, Microsoft Edge for example, can be removed but most can.
