I have removed the MS spyware store from my system. To install, upgrade, or uninstall an "app", I have to reboot into safe mode, enable those services, rename several directories, reboot again, install/uninstall/upgrade, then reboot into safe mode again to disable the spyware, then reboot again.
By using the MS spyware store, your product now has dependencies stretching into every tiny corner of the Windows system. If one little firewall or antivirus or update service isn't running, the install (or upgrade or uninstall) will fail. It is insane that I had to troubleshoot a firewall to install a photo editor. This is like if I had to mow my lawn to change the oil in a car.
