Right click on the folder in the registry on the left side, example right click on "Internet Settings"
Choose export and save the file, then do the same thing to the other section. Once done delete those two sections. Do not delete anything before them.
Then once done do a reboot and then once back up go to internet options, advanced and do a reset. Then test it and see how it does
If you dont feel comfortable doing that, you can go into the other user account you made where it works and export those two keys out so I can compare them to your current ones and see what I find to be different.
