    Windows 10 -Using Remote Desktop Services with a SHA256 (SHA-2)? How?


    Hello,
    I've searched the internet high and low to find the answer to this problem and have not come up with much.

    I have Windows 10 Professional and I run a remote desktop protocol in order to access my PC remotely. The self-signed certificated which is auto-generated by Windows (in order to support the TLS encryption) is SHA1. I work in the security industry and I understand that SHA1 is phasing out.

    What is the process to upgrade this auto-generated certificate so that it will use SHA256? The closest article I've been able to find is here: https://support.microsoft.com/en-us/kb/2001849, but it discusses replacing the RDP certificate with a custom SHA1 cert: it says nothing about SHA2.

    All the articles I can find about this refer to Windows Server 2008/2012. There is NOTHING about Windows 10.

    Does anybody know how to accomplish this?

    Thanks
    Bob

    Well it looks like I'm going to answer my own question.
    Sometime between 9/7/16 and 9/30/16, Microsoft released an update which apparently automatically corrected this.

    I checked and my RDP cert is now SHA256

    Thanks

    Which hotfixes?


    Hi

    I have the same issue, I was wondering if you may be able to give me a list of the hotfixes installed on your server during the time you mentioned so I can compare with ours? I can't find any info on recent Microsoft hotfixes that fixes this issue :-(

    Thanks.

    Hello,
    To clarify, this is not a Server edition, this is Windows 10 Pro.

    So I'm not sure which fixed it but one of two changes were made around that time:

    1) there was an extensive cumulative update at the end of September which I downloaded and installed

    2) towards the begging of October I got a new PC so I did a clean install, using a Windows 10 boot CD. I installled all the latest updates right away.

    Unfortunately I did not check the status of the cert until shortly before I posted my update here...

    Hope that gives some guidance.

    Good luck!
    Bob
