Thumbnail Handler Extraction Host Looping after Installing TLB

I guess I know how to recover. By default TLB store all toolbar settings, including menus and shortcuts, inside the Quick Launch folder: C:\Users\<your user name>\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch.

So you have to open this folder and delete the folder you've copied into TLB. Also I recommend to delete the any *.ini and *.xml files. Some of these files can be hidden. Or you can delete all files Quick Launch - this will reset TLB.

How to stop looping? You can restore pre-TLB installation point, or open the task manager (CTRL+SHIFT+ESC) and kill the process "explorer.exe" when it will appear. Windows restarts explorer.exe when it is crashes, but don't restart it if you'll kill it. Now select "File->Run new task" and click the Browse button, you can use "Select file" dialog as a mini-explorer. Navigate into Quick Launch folder and delete files. Or Open "C:\Program Files\TrueLaunchBar" folder and rename tlb.dll into something other, this prevent loading True Launch Bar (when you clear the Quick Launch folder, you can rename it back into tlb.dll).

Now you can run explorer.exe in the "Create new task" dialog and get desktop back.

Please can you backup the Quick Launch folder and send it to me support@tordex.com, if this folder does not contain sensitive information? I'll try to reproduce the bug here and fix it.
