I can't pin any Folder to Windows Explorer in taskbar

@Shawn: Thank you for your reply ^^
And yes, I made a big mistake as saying "pin to taskbar" instead of "to jumplist". Days ago, the folders which were supposed to be on my jump list of the pinned window explorer icon suddenly disappeared (even the recent used programs on my Start Menu disappeared too). I just... dont know why it happened to me ~.~
Now it becomes like this: If I open windows explorer by clicking its icon on the taskbar, "Taskbar" will appear on my jump list, which did not happen before. If I open any programs, the containning folders of that programs will appear on my jump list, which did not happen before too 0_0

I'm a bit late but I found the solution which worked for me. Got it from one of the comments here:
Pin to Taskbar and Pin to Start Menu Missing from Context Menu Fix

"One of your Delete or Clear Jumplist Recent Items in Windows 7 is corrupted in AutomaticDestinations-hidden system folder go to
%APPDATA%\Microsoft\Windows\Recent\AutomaticDestinations
YOu may notice one of the file is huge compare to the other. Delete that or just delete them all."

Jump Lists - Reset and Clear All Items


I deleted them all and it started to work instantly after that =)

Had a few items pinned in explorer icon, but no new item could be pinned. This solved my problem!!!

Thanks! :)

After nothing else worked to resolve this, including the steps listed in replies here, I discovered what the cause of the issue was for me, and resolved it.

I had modified the default windows explorer taskbar target, and needed to reset it to the deafult.

This is done by right-clicking the explorer/folder icon on the taskbar, then right-clicking on "Windows Explorer" in the pop up list, then clicking properties.

In the "Target:" entry, if you have anything other than the following (default) target:

%windir%\explorer.exe

...then pinning any new folders/shortcuts to the windows explorer taskbar list will not work. I had modified it to load my user folder recently because having the libraries folder as the default was annoying.

Once I changed the target back to the default %windir%\explorer.exe, I was able to pin other folders to the explorer taskbar list again.

Thank you tragicmike, that worked :)
It was already set like that so I changed it and applied the change then put it back to what it is supposed to be and it is working now :)
