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,

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.

I had exactly the same issue after removing IE the other day, so re-installed it. I just now changed the reg entry to Firefox, and it still seemed to work, so I then uninstalled IE again - mistake! That removed the whole open>command bit of the registry. I merged the reg file I had exported (with IE being called), to save re-creating the keys, then edited to open html with Firefox. After a reboot that works - with IE gone, hopefully for good.

I simply merged the old ie key/values, which were:

Code:

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\htmlfile\shell\open\command]
@=""C:\\Program Files\\Internet Explorer\\iexplore.exe" %1"
"DelegateExecute"="{17FE9752-0B5A-4665-84CD-569794602F5C}"

and edited the .exe to run FF. It now looks like this:

Code:

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\htmlfile\shell\open\command]
@=""C:\\Program Files\\Mozilla Firefox\\firefox.exe" %1"
"DelegateExecute"="{17FE9752-0B5A-4665-84CD-569794602F5C}"

I didn't know what to do with the 'DelegateExecute' bit so left it alone!

Looking at the post history, I wonder what made me respond to a post over a year old?
