Note: The apps mentioned above cannot stop anyone from pressing the power button on your computer to shut it down, thus losing any work that has not been saved, and switching it on again to gain access to your data unless Windows login is requested. Therefore, you should still create a local or Microsoft account to make sure that your PC is secure.
