Windows 8 desktop constant reloading, "thumbnail handler extraction host"

6,640

Problem solved! I simply boot up Windows with "safe mode with command prompt". I open notepad with cmd then click open file, I navigate to the Nikon installation folder(programs files) and then delete it! Windows is now working, I run ccleaner to ensure all remaining file is deleted.

I have recently install the Nikon NEF codec and the Nikon nx d viewer on a Windows 8 laptop, after I restart Windows this happens: after i get into the desktop, it shows a full screen theme colour(green I my case) and then reload all the thumbnails in the desktop. It goes into a loop of this.

I am unable to do anything like uninstalling the softwares because it cuts all the actions once it reloads. I have try safe mode but it does exactly the same thing!! The problems is a process called "thumbnail handler extraction host", which there is 80 of them in the task manager dialogue.

Please help! I am running Windows 8.1, i7 4510u CPU, 8gb ram and a gt750m gpu.

Note, I have tried using the system restore point, It said it cannot delete any file because it can't access the files. Second, I don't want to do a full system restore or refresh because I got lots of programs and files in it.

  Do you have Norton, AVG or any other antivirus/internet security package installed? I have seen this a number of times and uninstalling whichever of the AVs fixed it - especially Norton and AVG... you can uninstall and then re-install and the problem should be gone. If you keep getting the Metro interface popping up then you need to click the desktop icon the moment your computer starts - otherwise this will happen.

  Yes I do have avast av installed, but I have already disabled it from start up. And also it is not the metro screen since I use classic shell which skip the metro screen.

  I know it's a pain but if you can kill all the thumbnail extraction host instances via the Task manager then you will, at some point, be able to control your machine properly for a few minutes. It's a paint, I know, I've been there...
