How to disable Windows 7 Logon Background on Acer Aspire One netbook

I purchased a new Acer Aspire One netbook recently, and wanted to disable the Acer branded background that is shown when you get to the Windows 7 Logon Screen. Here's the steps to disable it (turning it back to default Windows 7 background):

1. Start -> search box, type in regedit and hit enter or click on it when it loads.
2. Navigate to HKLM->Software -> Microsoft -> Windows -> CurrentVersion -> Authentication -> Logon -> UIBackground
3. Change OEMBackground from 1 to 0.
4. Close regedit, and then log off. The registry key takes effect immediately.
