Windows 10: Bought a used ematic Windows 10 tablet

Found on Microsoft community forum; you could try this:

Follow the below steps:-
1)*** Press Shift and Restart from the power icon (together)
2)*** Select Troubleshoot.
3)*** Go to Advanced Options.
4)*** Select Command Prompt.
5)*** Type "net user Administrator /active:yes"
6)*** Hit Enter.

A user account with the name Admin will be created. Log in with that account and you will be able to access Admin privileges. You can also create and change the status of other accounts with that account.

Next restart should give you the choice to log in using the Admin account. (By default it has no password)

 

The problem with that approach is that you don't get to step 5 until after you've already typed in an Admin-level password for that machine. *Wink

In fact most of the options in a Shift-Restart are like that and require an Admin-level password (even the Reset option which I thought earlier might work seems to need a password).

But Shift Restart should allow you to
* get into the UEFI/BIOS settings
* Turn off the computer properly (ie not in 'Fast Startup' mode), which makes it easier to boot from a USB stick
* There might also be a Factory Reset option or similar which might not require a password (with any luck - not sure about that).

If you can't do a Factory Reset, I think you might need to create a USB with a Windows installation ISO on it, use Shift Restart/ Advanced Startup to boot from that, and then install Windows again.

 

I was assuming that an Admin password hadn't been set up *Redface

 

Not sure how easy this is to do on a tablet as they boot fairly quickly

But another thought is to crash the machine while its booting, force it off by holding the power button in while it starts up

After doing this about 3 times, windows should then give an error saying it had trouble starting, then give you the recovery options

 

The OP shouldn't need to do this: Shift - Restart from the logon page should get the same options more cleanly.
