1. There is a registry class in _FFC, which you can use for modifying the registry. Surely your users should not even attempt to do that.

I hope Vladimir will provide more thorough instructions.

Yes, the aforementioned registry class.

>2. The number "27" he finds in which registry value?

It sounded as a binary representation for the directory name, but I'm not sure.

>3. What indicates the found "731" -> this seems to be the final value he was looking for

Same thing, I guess.

>4. Now to change the Vid and Mode values in which registry entree?. I presume you shall have to change in case you want thumbnails the value of Vid to "{8BEBB290-52D0-11D0-B7F4-00C04FD706EC}" and Mode should be "0x5" (read the first 1. and 2. in his original message)

Koen,

I would probably wait a bit on this one. It's too late right now in Russia, but I hope someone will post updates to that solution soon and saves you the trouble and possible mischief :)

In any case, good luck!
