@042099g Were you running Opera as admin at the time? A regular user can't delete a file saved by a program running as admin - you'd need to run Explorer as admin.
@menko1437 And those two browsers uses different profiles directories? To do what you want, one of those browsers need to have been installed in standalone mode, otherwise they will share the same profile directory and, therefore, the same settings.
@bsod I did and it worked! It didn't delete any of my setting either, it only reset my speed dial page, but the wallpapers are already there for you to quickly choose. It also didn't touch the sites under the search bar. It was that easy, I can't believe why I didn't think about this. Thank you so much!!
