# PC-Tuning is a written guide to tuning a Windows PC, not a script

> PC-Tuning is a long, structured guide to configuring a Windows machine, from BIOS options and cooling through to registry tweaks, interrupt moderation and framerate caps. The primary language is PowerShell and the tree carries a bin folder, but the substance of the project is the document, and it opens by telling you to distrust it.

## The guide tells you to doubt the guide

PC-Tuning is described as configuring Windows based systems for a variety of tasks, and the primary language of the repository is PowerShell. The tree is small for a project of this size: a README, a LICENSE, an assets directory, a bin directory and a docs directory.

The README opens with three cautions rather than an introduction, and the first one sets the order of the whole document:

> In order of performance scaling, Hardware > BIOS > Operating System.

The other two are about method. The second says not to blindly trust or believe everything you read online, including this resource, and to typically doubt everything, validating statements through evidence, research and benchmarks. The third says not to apply random, unknown or undocumented changes, programs and scripts to a system without a comprehensive understanding of what they change and what impact they have on security, privacy and performance.

That framing is unusual and it is the most useful thing about the project. A tuning guide is exactly the kind of artefact where confident advice gets copied between machines until nobody knows why a setting is there. This one starts by telling you to check.

The licence is GPL-3.0, and the repository has no GitHub releases, so the document is read from the repository rather than installed.

## The table of contents is the argument for reading it in order

The README is essentially a long table of contents, and reading it end to end is the fastest way to understand the scope. The document runs in numbered sections: the table of contents, an introduction with other resources, benchmarking, physical setup, cooling, then BIOS/UEFI, then USB port layout, peripherals, stability and thermal performance, installing Windows, and configuring Windows.

The ordering is itself a recommendation. Hardware comes before firmware, and firmware before the operating system, which matches the scaling rule at the top. The benchmarking section sits early, before any change is made, which is the correct place for it.

The BIOS section alone has more than twenty subsections, and the names show the level of detail: partition style, BIOS recovery methods, BIOS microcode, accessing hidden options, unnecessary devices, ReBAR, hyper-threading or simultaneous multithreading, power states, SVM mode, TPM, CSM, Secure Boot, fast startup and hibernation, spread spectrum, legacy USB support, PCI link speed for devices, fan curves, and BIOS profiles and backups.

The Windows configuration section is the longest, and its subsections are equally specific: the file system, user account control, unrestricted PowerShell execution policy, process mitigations, registry options, privacy options, search indexing, scheduled tasks, optional features, power options, message signalled interrupts, XHCI interrupt moderation, kernel-mode scheduling, QoS policies, and application level settings such as NVIDIA Reflex, framerate limit and Game Mode.

## Recovery and backup are documented next to the changes

Two details in the table of contents are worth singling out, because they are the ones most tuning guides leave out.

BIOS recovery methods has its own subsection, which sits alongside BIOS updates and BIOS profiles and backups. That trio means the document assumes you may brick or misconfigure the firmware, and tells you how to get back. For a project that spends twenty sections telling you to change low level settings, that is the correct structure.

The same instinct appears in the Windows section, where a temporary operating system is covered under stability, hardware clocking and thermal performance. The idea of running a scratch install to test a configuration before touching the real one is the practical answer to the caution about not applying unknown changes.

Error correction has a subsection too, in the stability and thermal chapter alongside load-line calibration, GPU tuning and RAM and CPU clocking. Whether you need any of this depends entirely on the hardware, which is why the guide spends its first sections on physical setup and cooling before touching anything that a script could change.

## Peripherals get the same scrutiny as the processor

The peripherals section is not a list of driver downloads. It includes cleaning, onboard memory profiles, RGB lighting effects, DPI, report rate, polling stability analysis and monitor setup.

Polling stability analysis and report rate belong to input devices, and they are the sort of setting that sounds like a free win and is not. The document's own framing, that you should validate claims through benchmarks, is aimed directly at that kind of advice.

Onboard memory profiles are the interesting case, because they sit at the boundary between the hardware and firmware chapters. Setting the memory timings through the firmware profile rather than through an operating side utility is the same principle as the scaling rule at the top: change the thing that matters closest to the hardware.

The USB port layout section follows the same logic with a very practical shape. It has subsections for reviewing accessible USB ports, planning the layout and plugging in devices, which reads as a workflow for mapping the ports on a case and motherboard before deciding which devices go where.

## Windows install and configuration are documented end to end

The install chapter covers storage partitions, which Windows version to use, downloading and preparing a stock Windows ISO, ISO sources, ISO preparation, fetching required files and booting into the ISO. Then the configuration chapter starts with the out of box experience setup and works through the file system, user account control, the PowerShell execution policy, importing a bin folder, process mitigations on Windows 10 1709 and later, and merging registry options.

The registry options are split into their own subsections, one for documenting what each option does and one for applying them, which is the distinction this guide keeps making everywhere else in the document: know the change, then make it.

There is also a large section on removing what Microsoft did not ask you to have. Handling bloatware, decluttering the interface, adjusting visual effects, managing prefetch and Superfetch, hiding tray icons, trimming optional features including .NET 3.5, and choosing privacy options for Windows 8 and later.

The document also covers the things people forget: activating Windows, disabling hibernation, installing drivers, setting the graphics driver, MSI Afterburner, Process Explorer, the device manager, device power saving, and message signalled interrupts with XHCI interrupt moderation for the USB and audio controller and the network interface card.

## What a reader actually gets, and what they do not

The honest summary is that PC-Tuning is a document, not a tool. The tree has a bin directory and the primary language is PowerShell, so there are scripts somewhere, but the README does not say what they are, how to run them, or what they change, and there is no install step, no configuration file and no command line interface described anywhere in the front page.

That has a direct consequence for how you use it. If you wanted a script that applies a known good Windows configuration to a fleet of machines, this is the wrong repository, because the guidance is written for a person reading it on one machine, in the order the author recommends, with the intent that you check each change.

The same goes for performance claims. The document repeatedly sends you to your own benchmarks, and it does not publish a table of frame rates, boot times or throughput numbers. There is no benchmark result to cite here, and there should not be, because the project is explicit that measurements belong to the reader.

The maintenance picture is thin by design. The repository is not archived, the last push was on 2026-09-29, and there are no GitHub releases, so there is no version history to consult when a section changes under you. The document is read from the repository, and the section numbering in the table of contents is the closest thing it has to a version marker.

## Conclusion

PC-Tuning is worth reading for a Windows user who wants to know what each setting does and what it trades away, since the guide covers hardware, firmware and operating system configuration as one continuous document rather than a list of unexplained tweaks. It is the wrong tool for a scripted, repeatable configuration across a fleet, and it is not a source of benchmark numbers, because the project explicitly asks you to validate claims yourself. Before following it, read the BIOS and Windows sections in order, note which recommendations depend on your hardware, and back up your BIOS profile and your data before changing anything, since the guide itself treats recovery procedures as a first class topic.

## FAQ

### What does PC-Tuning cover?

The guide covers benchmarking, physical setup, cooling, BIOS and UEFI options, USB port layout, peripherals, stability and thermal tuning, installing Windows, and configuring Windows including registry options, privacy settings, power options and interrupt moderation.

### What order should I apply the PC-Tuning advice in?

The README states the order of performance scaling as Hardware, then BIOS, then Operating System, and the document follows that sequence with benchmarking and physical setup first. It also advises validating statements through evidence, research and benchmarks rather than trusting advice blindly.

### Does PC-Tuning include a script to apply the settings automatically?

The repository is primarily a written guide, and the README documents no install step, configuration file or command line interface. The tree includes a bin directory and the primary language is PowerShell, but the front page does not describe what any script does or how to run it.
