The “Microsoft Store” component of Windows 10 is built in as a vital communications function. Some users may wish to remove this facility (e.g., sometimes there is minor amount of advertising in this “sales-like” facility; or they feel they would never use it). The proper approach for the “store” is to corporately block access or for users to simply ignore infrequent communications from this facility.
Removing, uninstalling, or reinstalling Microsoft Store application in Windows 10 is not supported as documented below. It will break WIN10 and a re-install of complete O/S is required.
In Windows 10, we do not recommend removing or uninstalling the Microsoft Store app. This behavior is by design. If you uninstalled Microsoft Store by any means and want to reinstall it, the only Microsoft-supported method is to reset or reinstall the operating system, which will reinstall Microsoft Store.
IT professionals can configure, limit, or block access to Microsoft Store for client computers. See the following article for more information:
