I have a high end laptop that began installing windows 10, just after midnight last night. Currently 13 hours later it is only at 8% complete. It began the installation without my permission (I am confused by why this happened) - and in an area where there was low wifi connectivity, although it is now sat next to the router.

Tomorrow I am going to need to take a train journey, and the laptop will need to be shut down and taken out of the wifi network.

What are the reasons a windows installation may be so slow? Is there any way to speed it up? What are the risks of turning it off?
 
Hi friend! Here's link I found. Hope this works for you!
You may get more replies latter. I stopped it once with out it doing any harm.

It depends on how far along the upgrade has gotten… not very far by the sounds of it.

  • If you shut it down (or it just times out) during the looking for updates faze then nothing bad should happen and it will just keep looking for a connection back to Microsoft until it gets all the patches.
  • However one of the last steps on a typical upgrade is to partition off about 20 g at the back of the c drive in order to hold a recovery image and yes shutting down the system unexpectedly during that phase can cause damage to the boot registry that results in a failed upgrade.

In any event the system is not going to be able to perform any useful functions until its all sorted out so I recommend leaving it behind.
