On Windows 10, the “WindowsApps” hidden folder is available in the “Program Files” folder that contains the files that make up all the default applications, and it stores every app that you download from the Microsoft Store.
If you choose to save apps on an external hard drive, Windows 10 will also create another WindowsApps folder to store the files along with several other folders, including another folder with your account name, “WpSystem,” “WUDownloadCache,” and “Program Files” folder to enable the ability to run apps from a secondary storage.
The only problem is that the WindowsApps folder is protected, and if you try to revert the changes, the folder will stay on the external drive, and you won’t be able to delete it. However, there are a few ways to delete it and any remaining folders.
In this Windows 10 guide, we walk you through the steps to delete the WindowsApps and the remaining folders part of the system to save Microsoft Store apps on an external storage.
