If you cannot use the Windows Key + L hotkey because your keyboard lacks
a Windows Key, you can press CTRL+ALT+DEL and then <ENTER> (assuming you've
turned off the fast user switching), or you can create a desktop shortcut
with "%windir%\System32\rundll32.exe user32.dll, LockWorkStation" in the
target field. (It is case-sensitive, BTW.)
