Don't know how to reset my device

Windows 10 offers an easy way for you to reset your computer, without having to reinstall it manually (From the DVD).

To reset Windows 10:

1. Go to the Start menu -> Settings.
   
   

   
   
   

2. Select Update and Recovery/Security (depends on the Windows version).

4. Select Remove everything.
   
   

   
   
   

5. Choose whether to fully clean your drive or not.
     * Bear in mind that Removing files and cleaning the drive will take much more time than the option Just remove my files.
   
   

   
   
   

6. Click Reset to start the procedure.
   
   

   

Note: you may notice the option Restore factory settings on some computers. If you select it, will reinstall any applications your computer manufacturer installed on your computer.

Do not interrupt the process to prevent data loss. If you use a laptop, connect it to its AC Adapter.

If you use Windows 8(.1) and your computer starts misbehaving, and if you want to delete all the data stored on it (pictures, videos, sounds) consider resetting Windows. By resetting it you will restore the factory settings and delete personal data.

To reset Windows 8(.1):

1. Move the mouse pointer to the top/bottom-right corner -> Click Settings  -> Select Change PC settings

Note: You'll have to wait for approximately an hour for the process to complete, and the computer will restart a few times. Bear in mind that the full cleaning of the computer will take longer than Just remove my files.

Also, don't interrupt the procedure. If you use a laptop, connect it to the AC adapter to avoid sudden shutdowns.
