Enable Classic Logon Screen in Windows 7 Home Basic & Home Premium

If you want to enable the classic logon screen in Windows 7 Home/premium, you will need to modify a registry key, because Home does not include the Local Security Policy Manager.
Download registry file to enable classic logon screen in Windows 7
You can also do this manually.
1. Click on start and enter regedit.exe into the search field and click on the item that appears
2. Uncollapse the registry keys: [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System]
3. Double-click on “dontdisplaylastusername” in the right pane and then modify the value to “1″ to enable this option and hide the usernames of the last logged on users.
Or copy this into a notepad, save it with the extension .reg and execute it:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System]
“dontdisplaylastusername”=dword:00000001

Hide User Account In Windows 7 Home Premiums

So here is a quick guide on how to hide a user account in Windows 7.

*IMPORTANT: before preceding,  know that if you hide your only administrator account you may have a very hard time getting back into your system as an administrator or logging on at all. So proceed with caution and make sure and then double check and make sure again that you are hiding the correct account and that you are not hiding your only administrator account. With that out of the way...see below...

How to Hide a User Account in Windows 7

1) Click on the start menu and type in regedit

2) Select "regedit" from the search results and click yes at the UAC prompt.

3) In regedit navigate to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon\

4) Right click on the Winlogon folder and select "New" and then select "Key". Note your Windows 7 install may already have these keys that we are creating, in that case you can skip the next few steps.

5) Name the new Key: SpecialAccounts

6) Right click on the new "SpecialAccounts" Key and select "New" and then "Key"

7) Name this new Key: UserList

8) Now select the newly created "UserList" Key. In the right pane right click on an open area and select "New" and then select "DWORD (32-bit Value)"

9) Name this new DWORD the exact same name as the user account that you want to hide. So if the user you wish to hide is "joe", then name this value "joe"

10) Double click on the new DWORD that you created. A new window will open, set the value to "0" (the number zero no quotes) if you want to hide the user. You can set it to "1" if you ever want to unhide the account. Once you set the value click "OK" and close Regedit

The next time you reboot your computer you should notice that the user is hidden from the welcome screen. I tested this in the 64-bit version Windows 7 professional and the 32-bit version of Windows 7 Ultimate RC.
