+x Dan Danz - 21 September 2023 5:46 PM@pimjoosten If the Ex on the end of RegSetValue is what puzzles you, that's a common MS way of differentiating two versions of the RegSetValue (used to Set a new value in the Registry), with the Ex meaning Extended version (with more or different arguments, perhaps). As for the other thing you asked: why does it show up sometimes? I note that the operation performed in the second picture of your examples shows a modified Disk ID. And that's explained in this UserGuide/KnowledgeBase article:... as part of a clone or restore process, Macrium Reflect will recalculate the signature according to the table below. If the signature is recalculated, the boot configuration data (BCD) store is located and updated and the drive mappings in HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices\ are also updated if necessary. The whole article has more about why the disk id must be different.
