1 Open regedit, navigate to HKLM\Software\Classes\CLSID\{581FFA***********} (there can be several of those), find the path do DLL there.
2 Open command line prompt, navigate to the folder with DLL and run the following command: regsvr32 -u <DLL_NAME>
3 Reboot your OS (or just restart explorer.exe)
After that, the log files and the DLL (which is also stuck) could be deleted.
