Screen stuck on ‘please wait while we install a system update’

My laptop has been stuck on ‘please wait while we install a system update’ for four days. I’ve tried powering off and on again a couple of times.

Hello @DiArmani .
Many boot errors and other problems can be solved by reducing the energy stored in the hardware components. This procedure of reducing the stored energy is also known as a hard reset.
o Turn off the computer.
o Disconnect the computer from any port replicators or docking stations.
o Disconnect all peripheral devices, such as USB storage devices, external displays, or printers.
o Disconnect the AC adapter from the computer.
o Turn the computer over and look for the battery compartment door to determine whether or not your computer's battery is removable.
o Now to consume any residual electrical charge from the capacitors protecting the memory, perform the following as it is the basics of this:
If you see an access door to the battery compartment, your equipment has a removable battery. Remove the battery, press and hold the power button for 15 seconds, reinsert the battery back into the compartment and proceed to the next step.
If you do not see any access door to the battery compartment, your computer does not have a removable battery. On most laptops with a non-removable battery, press and hold the power button for 15 seconds to complete the restart and proceed to the next step.

1. Reconnect the AC adapter to the computer, but do not connect any peripheral devices.
2. Turn on the computer.
If a startup menu opens, use the arrow keys to select Start Windows normally and then press enter.
