For those of you who are curious about having video wallpapers, I recently read that you can have VLC Media Player play a video directly to the Windows wallpaper. In case you never heard of it, VLC is a free, open-source media player that is available for most platforms. Though the interface is nothing special, it is the only media player I know that can play pretty much any file I throw at it, without me needing to manually download the proper codecs. I highly recommend it.

Once you have it installed, here’s how to get the video wallpaper working:

1. Considering backing up your existing wallpaper, just in case.
2. Launch VLC.
3. Click Tools > Preferences in the menu bar.
4. Click Video in the left sidebar.
5. In the Display section, you’ll find an Output field. It will most likely be set to “Default”. Change this value to “DirectX video output”.
6. Restart VLC.
7. Open a video file. In my case, I tried an .AVI, and Windows automatically switched to Windows 7 Basic. This is normal – when you close VLC, your previous theme will return.
8. Right-click the video output you’re seeing in VLC, and select Video > Direct-X Wallpaper.

You should now be seeing the video instead of your wallpaper. VLC will be looking fairly strange during this, so I suggest minimizing it. If that interrupts the video, you can try making the window as tiny as possible. Either way, the VLC window needs to remain open. It is powering your wallpaper, and is still useful for the video controls. When you’re finished, repeat Step 7, or simply close VLC.

I initially discovered this trick by reading a Lifehacker article: Set a Video as Your Wallpaper with VLC.

Yes, I'm sure.

At first, I saw it as an acceptable comprimise for the sake of security… but after a while, it became clear that most the apps I use actually need Administrative access. I found myself forgetting to launch the shortcuts with Administrative privileges, and then I’d have to close the application, and launch it properly by right-clicking and saying “Run as administrator”.

Eventually, I grew so frustrated that I turned the feature off, just to avoid the hassle. For a long time, I went without it – and then we got new machines at work, and we were told to install Vista Business on all of them. Since it was a work machine, I decided to leave UAC enabled, for security’s sake. It wasn’t always pleasant; however, at least I knew my machine was more secure – and so the cost of having to right-click, and select “Run as administrator” was acceptable given that it was within the context of work.

I put up with it until, one day, I was checking out the Properties of a shortcut… when I discovered a checkbox I’d never noticed before.

This checkbox, when enabled, made it so the UAC prompt appeared automatically after launching a shortcut, rather than me having to right-click it, and select “Run as administrator”. This feature alone made me realize that UAC isn’t so bad. The real cost of using UAC was having to right-click the shortcut and select “Run as administrator” (for me, anyway).

I could hardly believe that I had missed this feature – but when I asked fellow developer friends of mine, I realized some of them missed the feature as well. This got me wondering… maybe there are others that still don’t know this?
