And to answer an earlier question.... and this point in time, I'm completely lost as to a solution.
I agree with Windows is Windows is Windows but this issues is so bizarre I am beginning to wonder.
Yeah it is a baffling one.

Have you Googled the issue to see if there's anything out there like what you're experiencing?

Earlier on in this thread I googled extensively and indeed that is where much of my possible solutions came from. In particular the idea of setting the camera via it's menu to a PTP setting instead of PC. This if I recall was on a user support Forum, I then contacted Canon Support and they told me that there was no Menu item to change this detail so that confused the issue somewhat. There's one outfit saying do this and Canon saying there was no facility to do it!
I have been thinking of this problem this morning and recall that the OP said that the Registry Key for the Canon cameras looked very different from the keys for the other makes. Just perhaps if the OP were to post a screenshot showing clearly the various keys we might be able to get Brink to put his "Magic Registry key" hat on and look at this for us. It does look like a slight anomoly with Windows Enterprise version as I think I understand correctly that the Canon cameras work OK with other Versions of Win 7. I wonder if it is possible that the Enterprise edition has a different Firewall and that is blocking the cameras? Does anyone think this might be possible?

Here are some screenshots:

If I boot into a WinPE CD/DVD/USB environment, open the registry on the local machine and delete the entire registry key the computer will work with the Canon Camera until you reboot. Once the key has been created and you reboot the camera will no longer work.

Update New Information: I have discovered why the camera does not work after reboots; Windows will NOT load the Windows Camera Driver. It is not in memory. If I plug in a Nikon camera which works correctly it will load the Windows Camera Driver and now the Canon will work just fine because the driver is already loaded. When I reboot the Canon will not work again because the driver is not loading. If I repeat the steps and plug in the same Nikon or another Camera then the Canon will work again. -WS

Well Brink has looked at it and he can't immediately see where the problem is.
One more thing to try. Can you boot up in Safe Mode and see what happens? Your A/V will not run in SM so perhaps the Firewall will be off too! Cutching at straws now but perhaps worth a try!

Have you looked into maybe a Windows update, or lack thereof, causing the issue?

Issue - *Solved* I Need help - Win 7 - losing drivers after shut down/reboot
Solution - *Solved* I Need help - Win 7 - losing drivers after shut down/reboot. Unfortunately the "fix" is vague, but the OP does indicate it was an update issue.

Then there's this post here, also indicating an update causing the problem - Must reinstall NIC and USB drivers after every reboot

Safe Mode: No difference
A/V Off: No difference
Firewall Off: No difference

The Windows Driver Foundation - User Mode Driver Framework service needs to be changed from MANUAL to AUTOMATIC. This fixes the Canon Camera issues.

For you command line junkies (like me) use this in an elevated Command Prompt:

Code:
sc config wudfsvc start= auto
This took me a very long time to figure out. -WS

Thanks for the update. BTW it this something particular to 7 Enterprise? Strange you had to do this to get the Canon's drivers to stay put

Thanks.

Great question: I am still trying to figure out why this setting is set to MANUAL on our machines and AUTOMATIC on the home machines (well only one checked so far) I have everyone checking their working machines a home.

I am thinking it was some security update?? Searching the internet, I have read that this service leaks a bit and will start using a lot of memory, plus it is vulnerable to some types of virus threats. How true that is I don't know just what I read. -WS
