  1. Can't validate certs on Windows 10 machine


    I recently had my help desk migrate my laptop from one domain account to an account on a different domain. There was a lot of copy/paste going on as I watched the process as well as editing in the registry. Needless to say, I have little faith in the help desk and I'm reluctant to reach out for help. I have been able to resolve all issues except for one.It seems that nothing requiring validation of certificates works. I can't connect via VPN, websites won't load, etc. For example, when I try to go to any website, I receive this:NET::ERR_CERT_AUTHORITY_INVALIDI am not an expert in how certs on

    :)

    See if cert is local machine or current user?

    There seems to be two cert managers. One for Current User at certmgr.msc and another for Local Machine at certlm.msc. From this site here: https://docs.microsoft.com/en-us/win...ificate-stores it says that Local Machine cert entries are also listed in Current User.

    What I want to know is, is there a way to tell if a certificate listed in certmgr.msc is Local Machine or Current User? Because deleting a certificate from certmgr.msc would also delete it from Local Machine if it exists as a Local Machine entry. This is especially a problem when you may have duplicate certificates or different Local Machine/Current User certificate entries.

    There doesn't seem to be a way within certmgr or certlm to check if a certificate is local to Current User or not. This is a problem when you import a certificate to both Local Machine and Current User, as it shows up only once in certlm.msc but twice in certmgr.msc with no difference between the two. You would not know which one to delete if you wanted to remove Current User's version only.

    Edit: Seems theres a few roundabout ways...
    Method 1: Check the store locations here https://docs.microsoft.com/en-us/win...tore-locations and see if you can find stores via their thumbprint...
    Method 2: in cmd type certutil (-user) -(view)store <name of store> as suggested here: Windows certificate stores | Blog. This is ok for seeing if there are specific certs in one store...

    Not sure why it has to be so roundabout... if anyone else knows of another method please do tell

    Windows 10 Tweaks

    As you may already know, Windows 10 (as well as Windows 8) allow you to log in with a valid Microsoft account, instead of creating a local account that only works on your machine. However, you may prefer to keep a local account for privacy reasons. If you do, though, some Windows 10 features—like Cortana—may not work. Despite the default behavior, the Windows 10 Store is not one of them. You can still log in to your Microsoft account for just the Store without switching to a full Microsoft account. The process, however, is not terribly obvious. To do so, follow these steps:

    • Launch the Store from your Start menu.
    • Click the user icon next to the search box.
    • Click “Sign-in” from the menu that appears.
    • Choose “Microsoft account” and log in like normal.
    • When the “Make it yours” box appears do not enter your password. Instead, click “Sign in to just this app instead.”
