Well its supposed to throttle unused apps in background, not slow entire PC. No I do not see the slider adjustment some talk about. Is this a new feature? Just looks to me that they created a notch up on power management to more aggressively save battery at the expense of performance. Not sure that’s a feature in my book? How would this be a positive feature if it slows everything, its significant enough for users to notice the speed more so then any battery savings. Counter productive if you ask me.

As it can be easily disabled on a global, or temporary, or per-application basis, it’s totally under control by the user.

M$ also advertise their powerful performance of super-expensive Surface Pro 4 Win 10 tablets with Intel i7 Skylake processors, 16GB of RAM and 512GB SSDs.

Seems, M$-Win 10 is a bit schizophreniac or have a split personality.

All of the Power Plans are still available in 1709, but MS has hidden all but the active plan in Control Panel>Power Options.  You can use Mobility Center to switch to another plan which will then show in Power Options and can be viewed and modified as in the past.

My desktop PC on 1709 still retains the full Power Options list as in the past.

I wonder if a post-install script ran a few days after installation of the update. It took a while to replace the power plans with the slider (and the Battery Sense feature was added to the slider as well). Oddly, HP’s power plan (which was active on my laptop at the time the change was applied) was left in there. Maybe the OS checks if the system is a mobile device first?

The only slowdown I noticed was due to heavy apps sending a good chunk of RAM used to the hard drive. That laptop has 4GB of RAM and it was present on 1703 as well.

Quick Edit: Looks like that some background apps are indeed moderated the OS (on my side anyway. Although the tab writes “Limited Power” (rough translation from Greek, take it with a grain of salt)). Most of them were simply sitting on the background (such as the Logitech SetPoint, Discord, some of Microsoft Edge’s processes, etc.). Maybe there are some criteria for it?

EDIT #2: Found this detail on the Microsoft Document @b linked:

Devices that have the High Performance, Power Saver, or any “OEM Recommended” power plans will not be disturbed during the upgrade process. If a user has any of these power plans selected when they upgrade to Windows 10 version 1709, there will be no change to their power plans, and they will not see the slider UX. Users can still configure their power plans in the same way they could before upgrading.

I did a clean install of 1709 and I then got the power control slider and I think the laptop is performing better with clean install then just upgrading from 1703? Sort of weird how Microsoft hid the power profiles in power settings, but did not in Mobility Center? Come on Microsoft make up your mind what your going to do. This sort of thing is just sloppy.
