The @FrancoisB method works for Win8 and Win7. To automate the solution:

1. Create a text file with the .reg suffix (DisableWinL.reg, for example)

2. Paste the following content and save the file:

   [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
   "DisableLockWorkstation"=dword:00000001
   

3. Open that file with RegEdit (double-click should work) to execute the change.

   This file can be copied to a new machine to repeat the process. And another one named something like "EnableWinL.reg" could be created that re-enables the Win+L key:

   [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
   "DisableLockWorkstation"=dword:00000000
