We've tested ArcGIS Desktop 10.5.1 and it has passed with flying colors.
We're going to push it out to all users tonight at 6pm. No need for you to do anything; it will update automatically.
You do need to check that it opens properly and works for you after install.
You do want to make sure that your start menu looks like the attached phote (w/"SDE 10.5.1" in the name). That will show that the GHE Windows Powershell script has also installed along with the software.
