If you’ve installed Windows 8 and the Remote Server Administration Tools, you’ve probably noticed that Server Manager loads each time you logon. I find this to be fairly annoying. Fortunately, there is an easy fix for now.
In Server Manager, click the Manage menu
Click Server Manager Properties
Check the Do not start Server Manager automatically at logon box and click OK.
Hopefully this is fixed between Beta and RC. I may bug it anyway.
