Hi, after upgrade an esxi5.5 to latest 6.7, i fond in my VM listing a Meesage that told me, that i have not chose the correct OS. To enable all futures please set OS to Windows 7. This is not correct, as Windows SBS2011 is Based of Server2008R2. So i think this Bug can result also in lower Performance. I upgrade also to ESXi 6.5 on an older Hardware and fond the same Bug.
