Windows 10: How do you add a local device certificate to the trusted store?

I have a problem writing to my NAS. The solution for Win 7 was to click on the Certificate Error certificate the device presents in the address bar of IE11, select View Certificates, click on Install Certificates, Click Next, Place all certificates in the following store, Browse and select Trusted Root Certification Authority and Click OK.

How do I do this in Win 10?

WM6 and trusted certificates - installing software

I am unable to install software on my T Mobile Wing. I have tried Microsoft Reader and Scrabble. Both times I get the message on my device:



“Installation was unsuccessful. The program or setting cannot be installed because it is not digitally signed with a trusted certificate”.



How do I add trusted certificates?

 

network attached storage windows 10 problem

I have an NAS to which my Windows 7 machines connect through a wired local network.

Initially I had a problem with the device not having a trusted certificate. This was solved by creating one on the device and importing it into the appropriate certificate store.

Now I am trying to set up Windows 10 to do the same as I cannot access folders on the NAS and there is no message given when I do.

I suspect that this lack of a trusted certificate in the Windows 10 store is preventing the access.

To prove this How do I import the certificate using Edge or IE11?

 

Ctrl Panel\Credential Manager\Windows Credentials

The username is computername\username. Don't forget the comp name prefix.

 

OK about the Windows Credentials but I still have a problem with the security certificate.
I also did not understand your 'comp name prefix' what is that?
After adding a windows credential and I try to access the NAS device with https://192.168.1.6/
I get a message
There is a problem with this website's security certificate.
Can you help?

 

comp name prefix means computer name in front of username. Sorry for the confusion - I was just trying to reinforce what I had already said.

Sorry, no idea what the security certificate problem is all about. Anything show up with a google enquiry?

 

Nothing that made any sense from Google.
I have found a way of doing what I needed. It means using IE.

Type Internet Explorer in the search box (the one that Cortana insists on using)
Internet explorer will be the top desktop app.
Start IE then
1. Browse to the site whose certificate you want to trust.
2. When told "There is a problem with this website's security certificate.", choose "Continue to this website (not recommended)."
3. Select Tools->Internet Options.
4. Select Security->Trusted sites->Sites.
5. Confirm the URL matches, and click "Add" then "Close".
6. Close the "Internet Options" dialog box with either "OK" or "Cancel".
7. Refresh the current page.
8. When told "There is a problem with this website's security certificate.", choose "Continue to this website (not recommended)."
9. Click on "Certificate Error" at the right of the address bar and select "View certificates".
10. Click on "Install Certificate...", then in the wizard, click "Next".
11. On the next page select "Place all certificates in the following store".
12. Click "Browse", select "Trusted Root Certification Authorities", and click "OK".
13. Back in the wizard, click "Next", then "Finish".
14. If you get a "Security Warning" message box, click "Yes".
15. Dismiss the message box with "OK".
16. Select Tools->Internet Options.
17. Select Security->Trusted sites->Sites.
18. Select the URL you just added, click "Remove", then "Close".
19. Now shut down all running instances of IE, and start up IE again.
20. The site's certificate should now be trusted.

I would have thought that MS would have modified Edge by now to do the same thing but so far I have not found a way to do it.

 

Well done. That could be useful for others.

Maybe you should say what NAS this problem occurs with to round it off?

 

The NAS in question is a very early NetGear RND4000 or ReadyNAS NV+ v1.
This does not support a file system which Windows of any flavour can backup to.
However it is very useful as a repository for images taken by non MS software and other things like videos, podcasts and photos.

Later models can ( I am told), but I am in no hurry to part with cash just to check!
