Notes

To unlock the Workplace Shell a call must be made to WinUnlockSystem through a different thread. This is due to WinLockupSystem not returning from its call until the call to WinUnlockSystem is successful.

A program will display a password entry dialog to be completed. The program will make a call to WinUnlockSystem with the HAB and password. The dialog displaying the lockup message should have the WS_CLIPSIBLINGS style.

If there are any LockupHoo functions registered, they are called by the system during WinLockupSystem.
