Removing the Windows 8 Start screen entirely

If seeing the Start screen once is still too much for your weak constitution, there’s another solution that automatically opens the Desktop after logging in: Simply addC:\Windows\Explorer.exe to your registry in the following location:HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run. This is very easy to do using Regedit, but there are guides if you need help.
