A few months later, I published a new version of Insomnia to satisfy the two most popular feature requests . Here's how I explained Insomnia's motivation at theenTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)http://blogs.msdn.com/b/delay/archive/2010/12/14/no-rest-for-the-weary-free-tool-and-source-code-to-temporarily-prevent-a-computer-from-entering-sleep-mode-now-available-for-net-32-bit-and-64-bit.aspx#10396630Sun, 24 Feb 2013 23:25:13 GMT91d46819-8472-40ad-a661-2c78acb4018c:10396630David Anson<p>WormyWyrm,</p> <p>Please see my comment here: <a rel="nofollow" target="_new" href="http://blogs.msdn.com/b/delay/archive/2009/09/30/give-your-computer-insomnia-free-tool-and-source-code-to-temporarily-prevent-a-machine-from-going-to-sleep.aspx#10396629">blogs.msdn.com/.../give-your-computer-insomnia-free-tool-and-source-code-to-temporarily-prevent-a-machine-from-going-to-sleep.aspx</a></p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10396630" width="1" height="1">http://blogs.msdn.com/b/delay/archive/2010/12/14/no-rest-for-the-weary-free-tool-and-source-code-to-temporarily-prevent-a-computer-from-entering-sleep-mode-now-available-for-net-32-bit-and-64-bit.aspx#10396623Sun, 24 Feb 2013 23:04:21 GMT91d46819-8472-40ad-a661-2c78acb4018c:10396623WormyWyrm<p>My windows 8 home edition laptop falls asleep when the lid is closed (causing audio to cut out) regardless of if this is running or not.</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10396623" width="1" height="1">http://blogs.msdn.com/b/delay/archive/2010/12/14/no-rest-for-the-weary-free-tool-and-source-code-to-temporarily-prevent-a-computer-from-entering-sleep-mode-now-available-for-net-32-bit-and-64-bit.aspx#10354360Sat, 29 Sep 2012 07:16:29 GMT91d46819-8472-40ad-a661-2c78acb4018c:10354360Jason<p>Nice little utility, computer kept on sleeping while downloading files using my download manager (IDM) and it was pissing me off. &nbsp;Was tired of always turning off sleep mode in Windows and then trying to remember to turn it back on.</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10354360" width="1" height="1">http://blogs.msdn.com/b/delay/archive/2010/12/14/no-rest-for-the-weary-free-tool-and-source-code-to-temporarily-prevent-a-computer-from-entering-sleep-mode-now-available-for-net-32-bit-and-64-bit.aspx#10353383Wed, 26 Sep 2012 12:34:48 GMT91d46819-8472-40ad-a661-2c78acb4018c:10353383Olly<p>Great tool thanks.

I use the PC either at home or in the office with colleagues and in both cases there is nobody who would have a need or would gain a benefit from snooping - there&#39;s nothing especially confidential on it.</p> <p>Anyway, following your advice I found a program called Mouse Jiggler which seems to do the job admirably.</p> <p>Cheers </p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10253407" width="1" height="1">http://blogs.msdn.com/b/delay/archive/2010/12/14/no-rest-for-the-weary-free-tool-and-source-code-to-temporarily-prevent-a-computer-from-entering-sleep-mode-now-available-for-net-32-bit-and-64-bit.aspx#10253113Wed, 04 Jan 2012 18:31:48 GMT91d46819-8472-40ad-a661-2c78acb4018c:10253113David Anson<p>Robey,</p> <p>The SetThreadExecutionState API Insomnia calls also exposes a ES_DISPLAY_REQUIRED flag which should keep the display on - however, the documentation explicitly says &quot;This function does not stop the screen saver from executing.&quot;, so I don&#39;t think it&#39;s quite what you want. I think there are other programs out there that fake moving the mouse pointer periodically to simulate user interaction and which would probably accomplish your goal of preventing the screen saver.</p> <p>That said, the automatic password protection of your machines may be part of your company&#39;s security policy, so it may not be worth trying to bypass it. :)</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10253113" width="1" height="1">
