I just got a Surface Pro 4, and did all the latest updates (firmware updates and 1511).

I went into Power Options, created a "Power Saver" power plan, then went into advanced power options to adjust the processor power options (to limit it).

Unfortunately, they seem to have changed things around; I'm missing many of the advanced power options:

Compared to my Surface Pro 2 (also running 1511), I'm missing many options; most notably the "Processor Power Management" options. You can see a sample here.

Does anyone know how to get these options back? I'd like to be able to limit the processor when I activate the Power Saver plan.

Unfortunately, I didn't check if I had these options prior to updating.

If you apply a registry tweak described in blog Restore Maximum Power State to Surface Pro 4 from FrogBoy, a new process power management will be available that you can set to max CPU to 99% to prevent the CPU from going into Turbo mode.

This is what needs to be added to the registry, the download provides this in a so called .reg file:

Windows Registry Editor Version 5.00

; Adds the Max CPU % back to the processor setting in power settings.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00\bc5038f7-23e0-4960-96da-33abaf5935ec]
"Attributes"=dword:00000002
