Can some one please help me understand what really happens when I
disable a device (say, my network adapter under network connections or
do not use this device from device manager). I understand that the
device will be disabled(I can not use) until I go back and enable it. I
want to know what the OS does in the background. Is this any different
for what bus (USB, PCI...etc) a device is connected to?

I googled quite a bit and did not find any clear answer, everything I
found shows how to do it not what happens in the background. If this
info is published some where, please send me a link.

Thanks!

When you disable a device in Windows you're telling Windows to ignore it.
The big difference is that you haven't uninstalled it. As an example: Let's
say you wanted to disable a network adapter (NIC) because you only use
wireless but didn't want to remove it permanently (by disabling it in the
BIOS for onboard or physically removing a PCI card). If you *uninstall* it,
Windows is just going to find the NIC again and you'll wind up having
multiple instances of the same thing. So you *disable* it instead.

I don't exactly know what you mean by "what happens in the background". That
sounds like a question for your computer teacher or maybe a programmers'
newsgroup.

The explanation given by "Malke" should be quite sufficient for you.

However, basically, all "Windows does in the background" is change a
registry value in the section that registers the given device, called
"ConfigFlags" from 1 to 0 that tells Windows not to enumerate this
device (to ignore it).

As Malke also said, this means the rest of the registration of the
given device can remain 'intact' so rather than have to reinstall the
device, you can simply re-enable it.
