HyperOS documentation

Everything you need to install and get the most out of HyperOS — the free, debloated Windows 11 25H2 gaming build. Start with the quick version, then dig into the detail below.

What is HyperOS?

HyperOS is a modified version of Windows 11 Pro 25H2, focused on gaming. It's built from a clean, official Windows image and then stripped of the parts most people never use — Copilot and Windows AI, telemetry, background bloat and ads — while the settings that matter for latency and frame pacing are tuned for you out of the box.

In short: it's still Windows and your apps and games run normally, it's just lighter, quieter and faster to respond. It's completely free — the project only runs on donations.

New to this? Read this whole page once before you install. HyperOS changes core system settings, and following the steps in order is what keeps your install healthy.

Before you start

Make sure you have the following ready:

  • A 64-bit PC with at least 8 GB of RAM and ~30 GB of free space.
  • A USB stick of 8 GB or more (it will be wiped).
  • A tool to make the USB bootable — Rufus, Ventoy or any other you're comfortable with. All free.
  • A backup of anything important — installing wipes the target drive.
  • Your GPU driver downloaded in advance — NVIDIA, AMD or Intel.
Try it in a virtual machine first. If you're not sure, install HyperOS in VirtualBox or VMware before touching your real PC. It's the safest way to learn the process.

Installation

The short version: make a bootable USB, boot from it, and let it install. Here it is step by step.

  1. Make the USB bootable

    Easiest with Rufus: pick your USB stick, select the HyperOS.iso file, leave the partition scheme as GPT / UEFI, and click Start. Prefer Ventoy? Install it to the USB once, then just copy the .iso onto it — no reflashing next time. Either works.

  2. Boot from the USB

    Restart the PC and open the boot menu — the key depends on your motherboard or laptop (commonly F12, F11, F9, F8 or Esc). Pick the USB drive in UEFI mode. Not sure which key? See the full table below.

  3. Install Windows

    Follow the installer. When asked, choose Custom install and select the drive you want HyperOS on. It will copy files and reboot on its own.

  4. First boot

    HyperOS skips the noisy setup — no forced Microsoft account, no OOBE questions. It lands you on the desktop with a ready local user called HyperOS.

  5. Install your GPU driver

    Install the graphics driver for your card (NVIDIA, AMD or Intel) and reboot. That's all most people need — you're ready to play.

  6. Run the toolkit Optional · advanced

    On the desktop you'll find the optional POST-INSTALL folder with extra tweaks and toggles (see the next section). It's aimed at users who know what each option does.

    These tools change system settings. They're optional and for advanced users — we take no responsibility if applying them breaks your PC. If you're unsure, skip this step; HyperOS already runs great without it.
Done! That's a full HyperOS install. If something went wrong — no internet, black screen — check the Drivers and FAQ sections below, or just ask us on Discord.

Boot menu keys

When you restart to boot from the USB, you tap a key to open the boot menu (to pick the USB) or BIOS/UEFI (to change settings like Secure Boot). The key depends on your brand — tap it repeatedly right as the PC powers on. Here are the common ones:

Desktop motherboards

* On some Acer and ASUS models you must first enable the F12 boot menu and disable Fast Boot in the BIOS. If a key doesn't work, tap it faster and earlier, or check your PC/motherboard manual — models vary.

Post-install toolkit

An optional POST-INSTALL folder ships on the desktop. Everything is a simple .bat you double-click — nothing runs on its own. The main pieces:

Toggle panel

Turn WiFi, Bluetooth, printing, the fax queue, Hyper-V, Remote Desktop and Windows Update on or off whenever you want.

Tools

Apply the MAX PERFORMANCE power plan, clean temp files, reset the network, make a restore point, or launch DDU for clean GPU driver swaps.

Programs

Quick links to Steam, Discord, browsers, MSI Afterburner and HWiNFO to set up fast. The Microsoft Store comes included and ready to use.

Windows Update is off by default for stability. When you want updates, use the toggle in the panel, update, then turn it back off if you prefer.

Drivers

Unlike some builds, HyperOS comes with network drivers already injected (Ethernet and the most common WiFi chipsets), so you should have internet right after install. Still, two things are on you:

  • GPU driver — install graphics drivers manually for full performance: NVIDIA, AMD or Intel. Grab them from the vendor site before you start, in case network needs setup.
  • Rare WiFi/LAN chips — if your network adapter isn't detected, install its driver from the manufacturer (Realtek, Intel, MediaTek, etc.). The toolkit includes a network-reset tool if the adapter acts up.
Clean GPU installs: if you're switching cards or had driver issues, use DDU (Display Driver Uninstaller) from the toolkit in Safe Mode, then install fresh drivers.

Anti-cheat & Secure Boot

HyperOS never touches game kernels or driver signing, so anti-cheats run normally. Kernel-level ones (FACEIT, RICOCHET, Vanguard) additionally need Secure Boot + TPM 2.0 — that's their requirement on any Windows, not something HyperOS changes.

  • EasyAntiCheat / BattlEye — work out of the box.
  • FACEIT — enable Secure Boot in your BIOS.
  • RICOCHET (Warzone) — enable Secure Boot + TPM 2.0.
  • Vanguard (Valorant) — needs SB + TPM; test it, as it's the strictest.
To enable Secure Boot and TPM, reboot into your BIOS/UEFI (usually Del or F2 at boot) and turn on Secure Boot and TPM / PTT / fTPM.

FAQ

Is HyperOS really free?

Yes — 100% free, always. It isn't a product and nothing is sold. The project only runs on donations, and supporters get thank-you perks like early updates and beta access.

Can I get banned for using it?

No. HyperOS is optimization, not cheating — it never modifies games or anti-cheats. Just enable Secure Boot / TPM for the games that require it.

Will my games and apps still work?

Yes. It's still Windows 11. Steam, Epic, your launchers, Discord, browsers and normal apps all run as usual.

Is there Windows Update?

It's turned off by default for stability. You can turn it on any time from the toolkit's toggle panel, update, and turn it back off if you like.

What about antivirus? Defender is removed.

Defender is removed to keep the system light and free of background scanning. Honestly, with common sense — only downloading from trusted sources and not running random files — most gamers are perfectly fine without any antivirus. If you'd still rather have one, you're free to install a trusted third-party AV. It's your call.

Do I need to activate Windows?

HyperOS doesn't include or provide any license or activation. Use your own valid Windows license as you normally would.

Is there a Windows 10 version?

A HyperOS build for the latest Windows 10 is on the way, for people who don't want to move to Windows 11. Join the Discord to hear when it's ready.

Something broke — what do I do?

Reinstall is always the clean fix. For smaller issues, use the network-reset and restore-point tools in the toolkit, or ask in the Discord — that's what the community is for.

Stuck on anything? We're genuinely happy to help — hop into the Discord and ask. No question is too basic, and there's no problem we won't try to sort out with you.
