Sometimes my machine wakes up by itself. I read about powercfg -lastwake, but this only shows the cause of the latest wake event.
Is there a way to look at a history of wake events and see their causes?

You can look at the event viewer, EventID 1 with Source Power-Troubleshooter. Example:
Log Name: System

Event ID: 1
Task Category: None
Level: Information
Keywords:
User: LOCAL SERVICE
Computer: ****removed****
Description:
The system has resumed from sleep.

Aha! I see this
Wake Source: Timer - svchost.exe– Razor Storm – 2015-09-08T07:41:23.507Does it show something behind svchost.exe in brackets to indicate which service is behind the svchost? – HoD – 2015-09-08T08:00:01.793
No, but I googled the message and people say one frequent cause is automatically scheduled windows updates. I checked my windows update settings and sure enough it is set to install at this time every night. I turned it off and it hasn't woken up by itself since. :) – Razor Storm – 2015-09-09T19:03:17.663
