The owner of my company has a Surfacebook with Windows 10.  Not sure what he did or how he did it, but he has removed permissions to the C:\ drive. Windows will boot up and can be logged in to.  Nothing will run and there is no access to any files/utilities/programs on the drive. No utilities can be installed. When I try to change ownership of the C: drive the system just hangs.


He deleted all other users to the system as well.


We can't access system restore and what he thought was a rescue disk seems like it just has a password key.


Any idea on how to take ownership of the drive and add in permissions to get back into it?

You should be able to access System Restore using a Windows 10 install disk created with the Media Creation Tool or by creating a System Repair Disk on another Windows 10 computer.


You may also be able to access the Advance Repair Options doing the following. 


  1. Hold the Power Button for 5 seconds or until the computer completely shuts off.
  2. Press the Power Button to turn the computer on.
  3. As soon as you see the rotating loading circle, press and hold the Power Button until the computer shuts off.
  4. Repeat this process 2 or 3 times until you see the Preparing Automatic Repair screen.
  5. Let the computer boot to the Automatic Repair screen.
  6. Click Advanced Options, and then select Troubleshoot.
