Remove Built-in Windows 10 Apps Using CCleaner (or PowerShell Command)
Windows 10 comes bundled with a number of built-in tiled apps like Calendar, Mail, Maps, and more. You cannot get rid of them in the usual way, so here are two ways to remove them.
If you right click on some of these applications, you will not see the Uninstall option. Microsoft may have uninstalled it for a good reason, so proceed with caution – you can probably keep these apps installed, although sometimes uninstalling (and reinstalling) can fix problems, so it’s good to know how.
The easiest way to uninstall them is to use the latest version of CCleaner that was recently updated to include them in the Uninstall menu. CCleaner is one of those apps that we recommend everyone to install anyway, so this is definitely your best option.
If for some reason you don’t like CCleaner, you can uninstall most Windows 10 apps using PowerShell command. Click the start menu and type “Powershell” to display the prompt, then run the command. For example, to remove Calendar and Mail, you would run:
Get-AppxPackage * windowscommunicationsapps * | Remove-AppxPackage
