//
// The information is stored under Explorer-specific key whose path is
// below. The interesting part is UserChoice subkey which is the only one
// we use so far but there is also OpenWithProgids subkey which can exist
// even if UserChoice doesn't. However in practice there doesn't seem to be
// any cases when OpenWithProgids values for the given extension are
// different from those found directly under HKCR\.ext, so for now we don't
// bother to use this, apparently the programs registering their file type
// associations do it in both places. We do use UserChoice because when the
// association is manually changed by the user it's only recorded there and
// so must override whatever value was created under HKCR by the setup
// program.
