corrupted explorer quicklaunch on windows 7 taskbar

hi, i'm running windows 7 ultimate 64bit.
it's some times already that the quick launch explorer icon on the taskbar stopped working properly.
see the attached screenshot..

libraries have disappeared, and the default starting position for explorer is set to the origin 8 installation folder. i guess that's the culprit.. but i'm reluctant to reinstall it now.

please note that running: %windir%\explorer.exe correctly opens the libraries view

how can i restore the default behaviour?
thank you

i fixed the origin8 issue simply changing the link target from the menu.

but now recent places and pinned places have disappeared too!
- recent
- pinned
- libraries
are missing. and the displayed icon isn't the right one (ok, this is easy to fix, but that's not the point. i wanna eradicate the problem from the roots)

In Folder Options in the General and View tab there is a Reset Default button and in View, there is a Reset Folder button. Try these options to see if that helps you. ... Thinkpads_User

Another fix I used with Vista, but did not need in Windows 7 is to increase the cache:

Using the Registry Editor:
Create a new DWORD called Max Cached Icons and set its value to 2048.
Restart the computer.

As noted, I did not need this for Windows 7.

these hints didn't help at all.
how could they, btw?
JohnBusiness Consultant (Owner)Commented:
Here is a registry patch I received from Microsoft for Vista, but I think the keys are there in Windows 7.

How could these hints and patches help?  Seeing libraries is part of folder view which you want to reset. If the patch below doesn't help then there may be something deeper that is the issue. You also say that the corruption may have come from something you installed. If you are sure of that, then the patch below won't help either.

Use care (check first) when making registry changes.  ... Thinkpads_User

ok, thank you. i'll give it a try now.. but:

Use care (check first)  when making registry changes

JohnBusiness Consultant (Owner)Commented:
The section above can be packaged as a .reg file and applied.

The -HKEy are key deletions, and the +HKEY are key additions.

Look up the keys in your registry to see what is there. Also look up BagMRU in google and see if any updaes especially for Windows 7.

now i've understood what this bagMRU is about and i'm not sure it has anything to do with my case. i can see running the registry patch should do no harm so i'll try anyway.

i've got a new hint .. the explorer shortcut is works good on other another user account i created to check. so the problem lays somewhere in my user settings
JohnBusiness Consultant (Owner)Commented:
Thanks for the update. While it is a pain in the butt, you might try re-creating your user profile.

the registry patch had no effect on the quicklaunch..

i won't re-create my profile. it's just not worth it
JohnBusiness Consultant (Owner)Commented:
Again, thanks for the update. I don't know if there is a way to correct a corrupt profile. I had a mild corruption in my own Windows 7 profile that I lived with for the better part of year (I could work around it). I purchased another hard drive and in December, I just rebuilt the system. Ultimately the results were worth it to me.

i've got news: at last i decided to waste some time uninstalling origin8 (something which takes some care)... and that solved my problem. now i can have a link to explorer on the taskbar, pointing to the libraries or anywhere else, with all its features (pinned and recent links).
so that's it...

i'll try reinstalling origin8 later, hoping it won't mess things up..

thank you for your support
