Hi,

Microsoft Disable TLS 1.1 and 1.0 support from azure virtual desktop.
you can run this powershell script for enable TLS 1.2 on Windows 7 and Windows 8 (be careful don't execute this on Windows 8.1 or higher).

    Is there a fix that you know of for windows 8.1? I have a client who is using that version of windows and You said not to run that script on that version. 

     

    I do have another client on windows 7 so I will try the above fix for that one. 

     

    Thanks for your help! 

     

    Cheers, 

    James

      The .NETFramework part applies to (and required) for Windows 8.1 too

      [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:0000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001

    jeep92 , very helpful. Thanks. I've had the same problem with another customer. Looks like Microsoft is disabling earlier TLS versions in waves? This problem was already reported 1st of July for my customer.

     

    Was there any official announcement done by Microsoft towards their AVD customers?

      No official announcement and the support (from azure portal and twitter) don't know this problem 😅
