Try this... Turn off the laptop. Then make sure there is no way at all for it to connect to the internet. If connected via Ethernet, unplug it. If there is WiFi, either turn off the WiFi or go somewhere where the device will have no way of connecting to that or any other WiFi. Then turn it back on.
If should load, if the problem was an update/installation issue. Which happens a lot with Windows 10. When one of the updates (updates come with reinstallations of systems as well) doesn't work, the system keeps trying and trying and trying. You have to cut off its ability to try accessing the update (accessing the internet) until the computer is fully loaded. Then it should be fine to be connected to the internet after.
