    Removed IE and now I cannot open hyperlinks in Outlook 2010

    I was reading an article today that stated there was a vulnerability that, even though IE was not your default browser, access could be gained by clicking on a file of a particular file type associate with IE. Since Microsoft has been encouraging people to not use IE I thought the sensible thing to do was to remove IE from my Windows 10 PC. After doing this I now have a problem where clicking on any hyperlink in Outlook 2010 fails with the following message:This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.I searched the internet and the solutions said to change the HTM and HTML default classes in HKCU to be htmlfile in both default settings. The only problem there is that the defaults are already set to htmlfile. I thought it might be the default browser settings or the default browser settings for the file types were messed up but they were both indicated that my default browser is BRAVE. I even tried to change my default browser to EDGE but that didn't work either. Short of reinstalling IE is there a fix or a registry hack or hacks that I can deploy to restore the ability to click on a hyperlink and launch my default browser whatever that browser might be? I'm hoping that someone has also removed IE and has figured out a way to make hyperlinks work.Any help would be deeply appreciated.

    Some older programs rely on IE to operate. One such is Microsoft Money which remains a very useful program. Office 2010 may be another,

    Fix error - The operation has been cancelled due to ...

    This problem is caused by problems in Windows and merely comes to light when a hyperlink is clicked in an Office application. The root cause of the fault is a Registry error regarding the handling of .html files.

    You can often fix the problem by reinstalling your chosen browser [Brave] and letting its installation procedure set up the necessary Registry keys correctly.

    The Microsoft KB on the subject is at Hyperlinks are not working in Outlook KB310049. You should use method 3.
    - Note that there is a stupid typo in it, the Registry key you need to check is actually HKEY_CLASSES_ROOT\.html [i.e. there is no space in the middle of it].
    - I think you have already tried step 3 of method 3 but the rest is also needed.

    - You can import the key by entering all this in a file and giving it a .reg extension then double-clicking on it

    Windows Registry Editor Version 5.00
    @="\"C:\\Program Files\\Internet Explorer\\IEXPLORE.EXE\" %1"

    - In the .reg file, you can change the IE reference to, for example,
    "C:\\Program Files\\Mozilla Firefox\\firefox.exe" %1
    and I imagine that the Brave equivalent is similar.

    This method is also covered at This operation has been cancelled due to restrictions - Slipstick

    If you have already tried reinstalling Brave** and the whole Microsoft KB Method 3 [and not merely step 3] then I do not know what else to suggest.
    ** Re-enabling IE instead might do the trick but I cannot see how it would be better than reinstalling Brave.

    I have never seen any reports of the standard fix not working.

    Instead of removing IE, which can potentially cause unforeseen issues, I followed the advice here from Farvatten:

    Thanks everyone. After reading everything I thought it best to reinstall IE and once I did the hyperlinks started working again. After that, I changed the "Open With" application for .mht and .mhtml files from IE to my Chromium-based browser and I could actually open the page I had saved. Not that I ever recall opening a legitimate .mht file but if I ever did I now know that I can open the file but I wont be doing so with IE thus avoiding the discovered risk.
