Windows 8 Wake-On-LAN Revisited

Occasionally over the past few months I have been unable to remotely wake my Windows 8 computer. I disabled the fast startup in power options to get Wake-On-LAN working in Windows 8. I recall the same computer (and past computers) waking more reliably when running Windows 7. I did a little research and found some more information in an official Microsoft support article:

http://support.microsoft.com/kb/2776718

Apparently, being able to wake a Windows 7 system after shutdown was not intended. Because "users expect zero power consumption and battery drain in the shutdown state", Microsoft has cut off power to all devices when Windows 8 shuts down. This does not explain how I am still able to wake my computer after shutdown, but it might explain why remote wake fails sometimes. I think that Windows 8 may shut down differently after it patches, but I have not found any evidence.

Based on the support article, I tried putting my Windows 8 computer to sleep a few times. Unfortunately, my computer appears less likely to stay asleep than it is to fail to wake after shutdown. When I return hours after putting my computer to sleep, I often find that it is already on. I'm not sure why the computer fails to sleep almost every time, and yet succeeds in waking remotely despite changes to the shutdown state.

I will continue to shutdown my computer, but I no longer trust that I will be able to wake it remotely every time. As smartphones increase in power and more data moves to online storage, connecting to my desktop is becoming more of a convenience and less of a necessity. Still, inconsistent Wake-On-LAN behavior is a source of frustration and disappointment with Windows 8. Hopefully, Windows "Blue" will be better.

Windows 8 Wake-On-LAN

For the past several years, I have relied on Wake-On-LAN (WOL) functionality to power on my home PC from anywhere. Whether simply in another room or traveling to another state, I have used WOL in combination with my phone or laptop to gain remote access to my files and programs. I have started keeping some files "in the cloud", but sometimes I need access to certain programs installed on my desktop computer.

I'm very excited about the new technologies emerging from Microsoft. I am anxious to acquire a Windows 8 Pro tablet when they become available. In the meantime, I have decided to install Windows 8 on my desktop computer so that I can code and test Windows Phone 8 apps. As I have been installing my developer tools and configuring the system, I tested whether I would be able to wake my computer remotely. The BIOS settings are unchanged and I had looked over all the power and device settings, yet my computer did not wake.

After some quick research this morning, I discov…

Windows Phone Composite USB Device Issue

As a Windows Phone developer, few things are more frustrating than when I lose time to "technical difficulties" that are completely unrelated to code I've written. When I recently tried to connect my Windows Phone to a new computer, the correct device driver failed to install properly. Windows 7 in its infinite wisdom substituted a generic device driver. From then on, my Samsung Focus was labelled as a "Composite USB Device" and was completely unrecognizable to the Zune software and therefore inaccessible to Visual Studio for deployment and debugging.

I really wish that I had taken screenshots to help others recognize if their issue matches what I am describing here. I can no longer take screenshots because I figured out how to resolve the problem, or rather, I nudged Windows into fixing the problem itself. I could uninstall the correct driver and try to duplicate the issue, but I have some software writing to catch up on. Just writing this up means that I'…
