I faced this problem today, and follow the instructions of Diparnak, and solve the error.
In my case, I downloaded NexusFiles, a utility Norton Commander Style, to browse two folder at same time and open the task manager to monitor de CPU usage.
1.- I Killed the explorer.exe process
2.- In Nexus, I moved all the files from the folder with problem (in my case, Downloads Folder) to a Temporal Folder.
3.- I moved only few files to Downloads Folder and start Explorer.exe process from File->Run in Taskmanager
3.a.- Open the folder with problem in Windows Explorer
4.- I monitored CPU Usage in Taskmanager, If it keeped low then i Moved others files... I did this until i found the file/folder with problem (Cpu Usage Raised 99-100%).
5.- I killed, again, the explorer.exe process
6.- I deleted the file/folder with problem
7.- I started the Explorer.exe process again
... and voila!
Thanks a lot Diparnak!
Sorry the bad english, please... pacience and good luck!
