J’essaie de analyse which group policies are inflating the bootup time. 
What’s the best way to do so?
Something like gpresult including timestamps/periods would be really helpfull!

Si vous are wondering what the hex numbers are on the left, those are thread id’s.
Si vous have multiple domain controllers and a distributed network, pay attention to le domaine controller that the GPO is processed from. It’s not unusual to pull a GPO from a domain controller that is different from le domaine controller that performed authentication, or a domain controller on the other side of the planet.
J’ai also found that Microsoft Network Monitor 3.4 provides useful information. Typically you would be able to observe each GPO as it is being processed, with a timestamp.
