I knew this used to be easy. It turns out the trick is to run IE as an Administrator:

Then browse to the website and click on the certificate details:

Then finally you can Install Certificate:

If you then want to export it to a file, it's a simple matter of exporting it from the Certificates (certmgr.msc) snap-in.

Solution 2

I recommend reading this KB article, especially the Import and Export sections. To summarize:

Press WinKey+R and at the Run window
Type in control inetcpl.cpl,,3 (there are two commas and the number three at the end, yes)
Click on Certificates button
Click on the Trusted Root Certification Authorities (or the appropriate tab for your certificate) and locate the certificate you want to export.
Click on the Export... button then Next
Select the format you want to save the certificate under and click Next
Type in a name. By default, exported certificate will be saved under your current profile's Documents folder. Click Next
Click Finish If everything went well, you should see a The export was successful pop-up.

Hope that helps.

How can I install a certificate from an untrusted website into the Certificates snap-in (certmgr.msc) of Windows?

I know how to do this with Firefox by exporting to a file and then importing it, but I'm looking to do this in IE or with any other way that's built-in to Windows.

The problem I had wasn't exporting it from the Certificates store. It was getting a cert from a website into the Ceritificates store in the first place.

Your question didn't say that. It asked: After browsing to an SSL-enabled website in IE, how can I export that SSL certificate to a file so that it can be later imported into the Certificates (certmgr.msc) snap-in? May want to edit and reword it. Just a suggestion.

@MichaelKropat - IE uses the Microsoft Store. So these instructions are actually correct as per how the question is currently worded.

@Ramhound how would you word the question? I've attempted to follow this answer, but the certificate I want doesn't show up on the Trusted Root Certification Authorities tab (or any other tab that I can see).

Cool, seems clearer. Updated.
