Why can't I delete these two files?

I just uninstalled firefox and installed google chrome. However I cannot delete these two files even after rebooting my PC

You can take ownership of folders or files, and have %100 access :P

i was gonna say that -.-

So this edits the registry? Or is this a hack?

It it a registry modification to allow you to right click a file or folder, "Take ownership", and will change the files attributes and securitiy settings. Your account will have full permisions of the file. 

I just tried deleting the files by changing ownership of the files within Windows to me. And now when I try to delete the files apparently I need permission from myself *facepalm*

I will now try the registry modification.

Ok the registry modification worked :) Next question is will this modification cause any problems or are there any known bugs with it?

Nope :P It is all fine :) Been using it for a long while

Glad i could help

Thanks :)
