Don't Sleep is a free portable app to prevent system shutdown, standby, hibernate, turn off, and restart.

Don't Sleep is especially useful with old programs that ran on Windows 7 or Windows Vista because of the more aggressive power-saving features with new rules.

Don't Sleep also prevents logging off, deactivating the monitor, or activating the screen saver.

Besides, Don't Sleep has a timer that allows time control to unblock or shut down the computer for a specified time.

Don't Sleep does not have to be installed and executed quickly from the desktop and carried on a small USB stick or other memory devices.
