disable user keyboard, mouse input ?

Hi @parlar good question. There is Win32 API function BlockInput. It can be used so (at your own risk):

import ctypes
from ctypes import wintypes

BlockInput = ctypes.windll.user32.BlockInput
BlockInput.argtypes = [wintypes.BOOL]
BlockInput.restype = wintypes.BOOL

blocked = BlockInput(True)
if blocked:
    try:
        pass # do something
    finally:
        unblocked = BlockInput(False) # unblock in any case
else:
    raise RuntimeError('Input is already blocked by another thread!')

If you start a script without BlockInput(False), then you unfortunately need to reinstall windows 10 inorder to fix this, or am I wrong? 🤔

The system will unblock input in the following cases:

• The thread that blocked input unexpectedly exits without calling BlockInput with fBlock set to FALSE. In this case, the system cleans up properly and re-enables input.
• The user presses CTRL+ALT+DEL or the system invokes the Hard System Error modal message box (for example, when a program faults or a device fails).
