Since the launch of Windows 8, we’ve come around the issues of automatically sign in on most of the popular discussion threads. This issue is discussed a number of times, however no strict solution is available yet.
After following many discussions, an apparent way that could easily resolve above issue is to make input of user name at the signing screen. But this seems not so easy. Since, either you have an option to input password for your local account or you can input password for Microsoft account.
If you are still confused with what I’m trying to do, here is the illustration. Look at the below screenshot, it shows you the usual sign in screen where the user name is already mentioned by Windows and you have to input the password only.
Now, lets clear the issue. Its the automatic sign in of the user and the reason is that the last user do not need to enter the user name on the course. So, if by any how we changed the above default screen to that shown in below screenshot, we have to enter the username too. The screenshot also unveils the switch to select which domain you want to use for sign-in. As already aware, this domain could be a Microsoft account or local account.
So without wasting your time anymore, finally let us share the way, to make this possible. This could be easily done with Registry Editor and Local Security Policy. So here are the ways:
FIX : Windows 8 Lets Last User Automatically Sign In Using REGEDIT
1. Press 
+ R and put regedit in Run dialog box to open Registry Editor (if you’re not familiar with Registry Editor, then click here). Click OK.
2. Navigate to this location:

3. In the right pane of this location, look for the DWORD named dontdisplaylastusername.Double click on this DWORD to modify its value, you’ll got this:
4. Set following values for the Value data section:

3. In the right pane of window, look for the policy named Interactive logon: Do not display last user name. Double click on it to modify. You’ll get this:
4. As it is already evident from the above images, that this policy is disabled by default, so in order to resolve the issue of automatically sign in, click Enabled in the above window. Click Apply followed by OK.
That’s it, reboot the Windows finally and you’ll be able to sign in with input of user name and password!
