Samsung mobile MTP device can not start (code 10)

https://forum.xda-developers.com/showthread.php?t=1797344
Go to the Registry Editor (Start -- Run -- "regedit" --  [ENTER]) Search the following key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\
If you click one of the few subkeys in class (e.g. {4D36E965-E325-11CE-BFC1-08002BE10318}) you'll find the string value (Standard) on the right side with a value (e.g. DVD/CD-ROM-Drives) You have to find the value "Portable Devices" on the string value (Standard) (In my case {EEC5AD98-8080-425f-922A-DABF3DE3F69A}, but I don't know if they are called always the same. Once found, you see a string value called UpperFilters --DELETE IT! Finished! Now your Samsung Mobile MTP Device should be recognized and even installed correctly right away. (The name of the device changed to GT-I9100 (Devicemanager) in my case...) Here an explanation about UpperFilters and LowerFilters if you want to know more:
