Rundll32.exe pop up everywhere in control panel

You won't lose anything.

It only takes 2 minute and it's completely safe: you can even undo it if you don't like it.

So since it is the safest, easiest, fastest, thing to try, that's my suggestion first.

Thanks guys. Since my version was newly re-installed the recovery really hit the spot. Even if it did not uninstall the programs the "programs and features" app did not have a single thing installed. Anyways, the recovery fixed the annoying window and I am thankful to all of you for your fast reply. The lesson I learned is to make a restore point when the computer is fully installed and functional, not before. Thanks peeps!

I'm posting a link to my image how to error really looks like with advanced tab open.

I think I would want to see the full command line but that might be hard with that message window.  Does anything show in the Event log when you cancel it?  Otherwise the only thing that I can think of is having Task Manager or ProcExp monitoring tasks which start with Ru (so for example, arrange to have the RuntimeBroker.exe showing), and having the full Command line available for display that way.  Further you would have to arrange that that display would be out from under that UAC prompt.  E.g. I'm not even sure if the message window is movable but I'm pretty sure it is modal.  FWIW I have just tested this idea with my Mouse Properties Desktop shortcut and it would work except that it doesn't matter for me because that dialog is non-modal.

Otherwise it looks like your shortcut is unnecessarily complex.  For example, here is my shortcut's Target:

Oh.  So, maybe yours is just a fully qualified version of mine?  Still, I would be more reassured to see the whole thing and know it wasn't trying to hide something.   <eg>

Good luck

I just can't simply restore. Last restore points are only Windows Critical Updates. Nevertheless, I have been using my computer only for a few weeks after re-installing because of this same problem. So basically I would lose all my valuable soft I installedthis week. Hoping to find a better solution :/

If the problem just began recently, you can restore Windows back to an earlier time, called a restore point. This restores backups of your registry and system settings, but doesn’t touch any of your files. It only takes a couple of minutes, and you can undo the process or try another date if it doesn’t fix the problem on the first try. When you aren’t sure where to go, this is by far the safest, fastest, and easiest option to try first.  This works best if you use it immediately after a problem shows up.  Waiting more than a week or two means the good backups can be too outdated to use.

1. Press +R to show the Run box, type RSTRUI and click OK.
2. Choose a date when the computer was working correctly, and click Next to restore the system files from that date.
3. Check to see if the problem is fixed. If not, you can go back to step 1 to either undo the restore process, or try another date.
