#11
Thanks for the reg file. As you noted, it looks good. I compared it to a Virtual Machine with a fresh install of W7pro64bit with IE11 and updates. Even though you are using IE10, there should be no difference for that key.
Do you know what might be preventing IE from changing the key that you removed?
You can run either or both of the hot fixes mentioned if you want... but I would sure feel better about the hot fixes if the webpage offering them said that they applied to IE10. Having a MS person say that they apply to IE11 is of some value, but if that is true, then MS should update those two web pages.
I've seen the hot fix mentioned under method 1 in that post applied to IE11 in threads in this forum. No harm seemed to come from it. I'm not sure if it fixed anything that a complete IE reset would not have fixed. You might try a reset first - including step 5. If that does not fix the issue, it is up to you if you want to try the hot fixes
