Windows 10 works very similar to previous versions of Windows. So much so, that Microsoft is promoting Windows 10 as a "familiar" experience. But, of course, there will be some minor differences, including how the UI works.
A good example is how previously you could tap Ctrl + Alt + Del on the PC keyboard to bring up the login screen. This is still possible for Windows 10, but it has to be enabled first. IT admins can use policies to enable it.
However, what if you're using a straight tablet? Something that doesn't have a keyboard and the Ctrl + Alt + Del key sequence has been enabled?
For tablets without keyboards, the following command sequence will work just like a Ctrl + Alt + Del procedure:
Windows button + Power button
Obviously, this requires a tablet that has an actual Windows button designed into it. Some manufacturers don’t include one, so be careful turning on Secure Logon for those.
