A utility for preventing Windows from falling asleep.

See doc for Russian: README.RUS.md.

The utility uses SetThreadExecutionState (kernel32).

SetThreadExecutionState is used to stop the machine timing out and entering standby/switching the display device off.

Command for help:

GSimpleWinSleepPreventer.exe -h

You can set the several manual modes of EXECUTION_STATE:

1. away (ES_AWAYMODE_REQUIRED)

GSimpleWinSleepPreventer.exe -es away

2. continuous (ES_CONTINUOUS)

GSimpleWinSleepPreventer.exe -es continuous

3. display (ES_DISPLAY_REQUIRED)

GSimpleWinSleepPreventer.exe -es display

4. system (ES_SYSTEM_REQUIRED)

GSimpleWinSleepPreventer.exe -es system

You can use multiple modes:

GSimpleWinSleepPreventer.exe -es continuous display system

You can set one of the quick modes:

1. monitor - prevent only monitor powerdown. Modes in use: ES_CONTINUOUS and ES_DISPLAY_REQUIRED.

GSimpleWinSleepPreventer.exe -m

2. sleep - prevent Idle-to-Sleep (monitor not affected). Modes in use: ES_CONTINUOUS and ES_AWAYMODE_REQUIRED.

GSimpleWinSleepPreventer.exe -s

3. awake - enable away mode and prevent the sleep idle time-out. Modes in use: ES_CONTINUOUS and ES_SYSTEM_REQUIRED.
