Updating SSL cert for Windows RDP server

If you have a signed SSL certificate from a trusted authority, you can use it to prevent Windows from popping that annoying “this connection isn’t trusted” dialog when RDPing into the box with the cert’s hostname. Thanks to this post on StackOverflow.

wmic /namespace:\\root\cimv2\TerminalServices PATH Win32_TSGeneralSetting Set SSLCertificateSHA1Hash="THUMBPRINT"

Where THUMBPRINT is the certificate thumbprint you can find from the certificate manager certlm.msc tool.
