Remove Efficiency Mode from Being applied to a Process

If you like me, have noticed the extremely detrimental effect that efficiency mode can have on a process, you probably want to disable it, right?

But, all the articles and posts online only show you how to disable it through the Windows task manager and it can only be done per specific process or sub-process.

For programs like Obsidian, Chrome, Firefox, or any other applications that leverage sub-processes, this is nearly useless. 

Even when you do, it just comes right back and there is no setting in either the application or Windows settings to just disable this "efficient" mode. 

Here is how I've worked around this in hopes that it helps others. 

First download and install Process Hacker 2:

Once you've installed Process Hacker 2, run it and find the process you want to disable efficiency mode for, right click on the top-level main process you want to ensure efficiency mode will not apply to.

















Select and apply a normal priority and the "Save for [application]" option to ensure it sticks to that.

Windows will not apply efficiency mode to any process running above low, so this should keep it from being applied to the processes you've now applied the priority to; you may see it still apply after a restart and may need to repeat the process but this was the most manageable method I was able to come up without looking to modify registry values and disable the efficiency mode more directly.

Proof of Concept or Get the Fuck Out

Site: https://www.alchemistowl.org/pocorgtfo/

A Journal I wholly recommend to anyone that is interested in reverse engineering, ethical hacking, and exploit prevention.

The journal does a wonderful job of going over so many interesting exploits, bugs, and techniques from over the years and does so in a tone and attitude that makes it enjoyable as a more leisurely read than a set of technical documents.

Additionally if you would prefer a hard-cover option, there is a HardCover or Kindle option for a lot of the articles by Manul Laphroaig on Amazon.

PoC || GTFO

This highly anticipated print collection gathers articles published in the much-loved International Journal of Proof-of-Concept or Get The Fuck Out.

PoC||GTFO follows in the tradition of Phrack and Uninformed by publishing on the subjects of offensive security research, reverse engineering, and file format internals. Until now, the journal has only been available online or printed and distributed for free at hacker conferences worldwide.

Consistent with the journal's quirky, biblical style, this book comes with all the trimmings: a leatherette cover, ribbon bookmark, bible paper, and gilt-edged pages. The book features more than 80 technical essays from numerous famous hackers, authors of classics like "Reliable Code Execution on a Tamagotchi," "ELFs are Dorky, Elves are Cool," "Burning a Phone," "Forget Not the Humble Timing Attack," and "A Sermon on Hacker Privilege." Twenty-four full-color pages by Ange Albertini illustrate many of the clever tricks described in the text.


PoC || GTFO Volume II

The International Journal of Proof-of-Concept or Get The Fuck Out is a celebrated magazine of reverse engineering, retro-computing, and systems internals. This second collected volume holds all of the articles from releases nine to thirteen.

Learn how to patch the firmware of a handheld amateur radio, then emulate that radio's proprietary audio code under Linux. How to slow the Windows kernel when exploiting a race condition and how to make a PDF file that is also an Android app, an audio file, or a Gameboy speedrun. How to hack a Wacom pen table with voltage glitching, then hack it again by pure software to read RDID tags from its surface. How to disassemble every last byte of an Atari game and how to bypass every classic form of copy protection on Apple ][.

But above all else, beyond the nifty tricks and silly songs, this book exists to remind you what a clever engineer can build from a box of parts with a bit of free time. Not to show you what others have done, but to show you how they did it so that you can do the same.



PoC || GTFO Volume III

The International Journal of Proof-of-Concept or Get The Fuck Out is a celebrated collection of short essays on computer security, reverse engineering and retrocomputing topics by many of the world's most famous hackers. This third volume contains all articles from releases 14 to 18 in the form of an actual, bound bible.

Topics include how to dump the ROM from one of the most secure Sega Genesis games ever created; how to create a PDF that is also a Git repository; how to extract the Game Boy Advance BIOS ROM; how to sniff Bluetooth Low Energy communications with the BCC Micro:Bit; how to conceal ZIP Files in NES Cartridges; how to remotely exploit a TetriNET Server; and more.

The journal exists to remind us of what a clever engineer can build from a box of parts and a bit of free time. Not to showcase what others have done, but to explain how they did it so that readers can do these and other clever things themselves.
