This is basically an admission that the Windows controls for CPUs aren't refined enough.

FYI I guess some people have been having problems installing the custom profile, AMD Robert posted this over on reddit:

Enthusiasts should be ecstatic over the responsiveness and two way communication between end users and the CPU manufacturer. There's nothing but upside for Ryzen.

Look at it this way
I see your point, but i also challenge you to think about what Intel has done for you. AMD being a smaller company in general have released a NEW technology based on existing foundry processes that incorporate more cores for more performance and they are doing it for YOU at a lower cost. I can't imagine their profit margins are anything close to an Intel using plain common sense. Intel has had years of the same architecture out and no real new breakthroughs in design or performance. Now they are cutting corners with cheap TIM so de-lidding is the only way to get a cool CPU with the Kaby Lakes. The new Ryzen CPU architecture is awesome, completely new, and will become faster once platforms can learn to utilize its cache technology and core scheduling. They drove prices down while getting the closest i have ever seen them to Intel in terms of performance. To expect any more than this on a new platform at launch is simply delusional. Heck if you game at 4k there is no difference at all!

To be fair Intel Skylake and KabyLake also have Windows 10 power plans issues. In Skylake and KB there is a little talked about CPU feature called Speed Shift which is directly tied to Win 10 power plans but utilizes the CPU for power decisions.
Only just recently have some manufactuerers actually added the Speed Shift support to the bios. Win 10 has had it for about a year now. Anyhow needed both...like I said this is a little talked about feature. For all system it provided better CPU power management as the CPU is in control it also reduces system latency by up to 150 ms from the few testing I have seen.
Now getting to the point of this and how it AMD is also in this....the Win 10 power plan settings that AMD changed are the same ones needed for Intel SpeedShift...go figure.
The issue with the windows 10 power plans is all the particular options are hidden by default by Microsoft and the defaults that MS uses are not any where optimal.
As I have learned over my year and half quest into Speed Shift info, is you can indeed unhide these options and adjust them in windows via powercfg commands in an admin prompt. What I have not figured out is how to actually test the changes in a home environment.
I would refer technical AMD users to several website for more info on both all these commands as well as take a quick read of the only "speed shift testing" I found. Only reason I am saying this is the parallels of the power cfg options are the same that are being adjusted.
Very Helpful Powercfg at MSDN:

Speed Shift Testing ( note this does not get into the power cfg needed)

This thread in another forums had some people actually uncovering the Power cfg needed for speed shift.
http://forum.notebookreview.com/threads/dell-xps-speed-shift.796891/
It is this last one that also after reading the release from AMD on the Ryzen Power plan that showed me the same power cfg settings that windows 10 and microsoft set as default are bad for both AMD and Intel...and both need these changed for better performance for different reasons.
Sorry I kind of rambled, getting old these days.

If someone still has issue with installation...
Just unpack (7zip) it and open admin command prompt to its location: ""..\Ryzen_Balanced_Plan\DataAsset\2\Ryzen_Balanced.pow_2a73e"
use command:
powercfg /import ""
Let's pretend that you copied "Ryzen_Balanced.pow" into D:\, command would look like:
powercfg /import "D:\Ryzen_Balanced.pow"
= = = =
Btw, does anyone here know how to edit "pow" files outside of windows power plan settings? There are some options which are not available for editing in standard windows power options.

Custom power plan doesn`t necessary mean that it has some new settings. It can also mean that it has customized values for a standard settings.

^ I am perfectly happy with power plans as they are (since I have way to edit them to my liking).
Power plan is such tiny peak of an iceberg. To me the OS kernel using features of CPUs on 100% looks more important.

The minimim and maximum cpu performance values in the new power profile were set to:
Min: 90% ?
Max 100%
I've dropped the Min value to 5%.
Will test and see if the cores are ramping up correctly, and then dropping back down etc.
