To figure out when your PC was last rebooted, you can simply open up Event Viewer, head into the Windows Logs -> System log, and then filter by Event ID 6006, which indicates that the event log service was shut down—one of the last things that happens before a reboot. This technique won't help you figure out when there was a power outage, but you can filter by Event ID 6005 to see when the system was last turned on—that event shows when the event log service was started again.

It's a simple tip, but could come in handy if you come back to your PC and want to figure out whether Windows Update or somebody else restarted your PC in the middle of the night, or you're just curious how many times you've rebooted in the recent past.

Once you've downloaded the Universal Darkroom script, which requires that you've already installed AutoHotkey, you can simply double-click on it to start up the application—there's no code tweaking required at all. It's very user-friendly, and even has a help window that hovers on the screen with instructions on how to use it.

To enable the darkroom effect for a window, simply right-click in the corner of the screen, choose Define New Border, select the window you want to use the effect for, and then tweak the borders to show or hide as much of the application as you want. What makes this script especially slick is the way it handles switching back to a different application—as soon as the "darkroomed" window loses focus, the black border will animate away, and then back when you switch back to the application.

We're providing you with a download of the script, which can also be found on the forum thread linked below. Universal Darkroom works on Windows, requires AutoHotkey. Impressive script, Liang!
