History of CPU usage for all processes

Question

How can I view historical CPU usage for all the running processes in Windows, including those processes that were started after the history collection had started? I am interested in a way to collect this information automatically.

In Windows 7 there is the Performance Monitor.

You must enable it, set the log options and then leave it running. It is only historical for as long as you run the application.

The file is :C:\Windows\system32\perfmon.exe

The tool to use is Process Monitor:

Start Process Monitor
Set a filter if required, otherwise uncheck all defaults and click OK to trace all
Enter menu Options > Profiling Events
Click "Generate thread prof‌iling events", choose the frequency, and click OK
To see the collected historical data at any time, enter menu Tools > Process Activity Summary...
Sort the list as required; double-click any one process to see its history.

Be prepared for a very large log file.

For a nice description of the above with screenshots see this answer.

For Win10 universal apps (not Chrome/Edge for now..), Task Manager nowadays got [App history] tab with CPU time that seems not just simple delta with start time:
