Works, even when your IT department has set Group Policy to lock out the computer after 3 minutes of inactivity (tested in Windows 10). Every other keep-alive program I've used has been defeated by Group Policy settings, so this is a big productivity enhancer. Just be sure to responsibly lock your system when you are actually away from keyboard.

Initial license key did not work, emailed support, and had a good key emailed back in 60 minutes. Works for 5 days without activation, so if there are any errors, there is time to get a good license key.

Otherwise this is flawless. Painless install for single account does not require Admin privileges.

The only complaint I have is that I would like to be able to uninstall and move this to another PC as needed (my hardware changes frequently depending on where I'm assigned). But this is dirt cheap, so it's not the end of the world to buy another license.
