Today I found that I can't aceess help on system tools through "Tool Help" button. It opens help window which says:
Can’t reach this page
- Make sure the web address //ieframe.dll/dnserrordiagoff.htm# is correct
- Search for this site on Bing
- Refresh the page
I am afraid it is Windows October update in action. Does anybody know how to fix this?
I tried profile reset and repair installation, no luck.
It is Windows 10 I worry about. The October update was delayed, because it was deleting files on PCs.
