The driver \Driver\WUDFRd failed to load for the device... error  

Hi, I am afraid I dont have an answer, I have noticed that certain devices seem to randomly revert the setting back to manual again. My GPS unit ALWAYS changes it, my camera and certain USB sticks will sometimes change it back to manual. I really have no solution other than keep chaning it back to automatic. I notice that on Windows 8, the default setting for the service is Automatic - Delayed Start, I have not tested it, but it might be worth trying this setting to see if it helps. It's a very odd thing, and probably just a strange Windows 7 quirk.

Thanks, Idaho. Worked great.

I would like to thank you, this thread has now helped me on more than one occasion. Installed an SSD recently & forgot to make Windows Driver Foundation automatic.

The UMDF reflector was unable to complete startup because the WUDFPf service was not found. This service may be started later during boot, at which point Windows will attempt to start the device again.

Above suggestion appears to have once again fixed the problem.

Seven Forums is the most helpful forum I have come across for Windows 7 related issues.
Thanks again to all who contribute.:)

In my case it was also an SSD (Adata brand). I would like to add one thing: please make sure your SSD has the latest firmware. This can avoid a lot of problems.

Very well spoken, newpgm! I couldn't agree with you more! Thanks to everyone who contributes!

Update: it wasn't my SSD causing problems in my case, it was an external hard disk enclosure (basically a box in which you can put any hard disk):
Conceptronic Grab'n'Go CHD3SU - Storage enclosure - 3.5" - SATA-300 - USB 2.0
(link to their website: here)

The problem is I had set the Windows Driver Foundation - User-mode Driver Framework service to Automatic and everything worked fine, however, that external hard drive somehow set it back to Manual.

For now I have disconnected that external hard drive and everything seems to be fine.

It's amazing this thread continue to help people, LIKE ME!!

First of all, THANKS!!!

Secondly, I can't believe Microsoft still has not resolve this issue in their own updates. UNBELIEVABLE!!!!

Thanks Idahosurge, it solved my WUDFRd prob as well!
