This page is a work-in-progress and will be updated.
This article is partially based on RessourectoR’s (admin of cs.rin.ru site) article:

I highly recommend to open and read it at least one time. It’s more complex than this page and covers more security topics.
What are Hypervisor Cracks?
Denuvo Hypervisor Crack or Bypass refers to advanced techniques that leverage virtualization at a very low level (often using a custom or modified hypervisor) to interfere with how the protection monitors the system. Denuvo relies heavily on integrity checks, timing analysis, and detection of debugging or emulation environments. A hypervisor-based approach allows an attacker to sit “under” the operating system, transparently controlling CPU behavior, intercepting instructions, and masking signs of analysis without modifying the protected executable directly.
Instead of patching the game binary, the hypervisor can emulate or alter specific CPU instructions, fake timing results, or hide breakpoints and memory changes, effectively tricking Denuvo into believing everything is running on a normal, untampered system. This makes the protection much harder to detect or react to, since its checks are being handled outside its visibility. These methods are extremely complex and are typically explored by highly skilled reverse engineers, as they require deep knowledge of CPU virtualization, kernel internals, and anti-tamper mechanisms.
Officially, only signed drivers can work at such low level. Due to the piracy nature of Denuvo Hypervisor drivers, they will never receive Microsoft-approved certificate. And that’s why to use such “cracks” you need to make certain modifications to your system security settings, listed below. Please note, that those changes are intended to be made temporary, for the course of your gameplay session and then should be reverted after you quit the game.
Windows virtualization-based security components
On modern systems with Secure Boot, TPM 2.0 and hardware-assisted virtualization capabilities, Windows 10 and 11 enable, mostly* by default, various security solutions via Virtualization-based Security (VBS). VBS is an umbrella term for using a bare-metal hypervisor, the Windows hypervisor, to create isolated virtual spaces that are safe from even a fully compromised OS, in which these security components run and monitor the OS or store confidential information.
The following Windows components are such security solutions:
- Memory Integrity (HVCI): Runs checks to detect malicious or at least unexpected modifications of Windows kernel code and restricts suspicious kernel memory allocations. For example, RessourectoR imagines this could protect against malicious software that is being run with administrative privileges and attempts to modify system files, or against memory security vulnerabilities in user-run applications.
- Credential Guard: Stores access credentials, such as passwords, authentication data, biometric data etc. in an isolated environment.
- Windows Hello: Allows you to log in with convenient methods like a short PIN, facial recognition or fingerprint scan. RessourectoR has not found a direct source for this, but it probably prefers Credential Guard to store its highly sensitive data. The login methods it provides tend to break when some of the components above are disabled. It is also protected by System Guard, if that is enabled.
- System Guard (Secure Launch): An advanced system hardening framework that protects the OS boot process and System Management Mode (SMM, commonly used by the BIOS to run hardware configuration software) from (arguably sophisticated) rootkits. Such rootkits could compromise the hypervisor itself, so this protection is assisted by various hardware security features of modern processors. Backed by TPM 2.0, this also allows to monitor system integrity, including the other security components mentioned here, after boot continuously and verify it from a remote system.
- From what RessourectoR could find, this is cutting edge and not enabled by default.
* Even though hardware and boot requirements are met, Windows sometimes seems to fail at enabling features that are supposed to be enabled automatically, such as VBS and memority integrity.
Without the Windows hypervisor, none of these security features can be used. By design, the hypervisor cannot be disabled directly. Instead, all the above features that want to utilize VBS signal that it needs to be enabled, which then loads the hypervisor. Therefore, we must disable all those features to prevent the Windows hypervisor from being loaded.
A boot option that prevents Hyper-V from loading the hypervisor also needs to be added.
I want to play that new Denuvo-protected game, is it safe to disable all this and use a hypervisor crack?
There is no simple answer. This is RessourectoR’s personal take as someone with 10 years of experience in security-focused system administration and only a casual interest in gaming.
It’s true that the most common threats are info stealer malware from fake download buttons, ransomware that encrypts your files or joining a DDoS botnet. It’s supposed such malware is usually not interested in higher privilege escalation or hardware sabotage, if it can already access what it needs. It’s also true that the best protection against such malware is a good ad blocker, staying on trusted sites and user education.
More experienced PC users develop a false sense of security from seeing how successfully they avoid malware infection by “being smart”. They argue that they don’t need all these restrictive, patronizing security features and AVs that just annoy with false positives, because their malware-free track record “proves” that they know better. They also argue that more advanced threats are not aimed at home users, but corporate networks and too unlikely to care about. Especially relevant for gamers: Virtualization can reduce system performance and whether that is noticeable or not is also a point of contention.
The other side of the argument: You would be disabling technology that evolved from decades of security research, ignoring what experts consider necessary nowadays. You would willingly give up protections against common classes of software vulnerabilities and if you ever do get a more advanced malware, it can breeze right through so that your PC can stay part of a botnet for eternity or spread to more local network devices more easily. If a lot of people remove these protections – especially DSE and memory integrity – for gaming, one of the main use cases of Windows PCs at home, it might be worth the effort for malware authors to target such setups. Widespread usage of HV cracks could encourage manipulated fake releases, because people who download those can be expected to disable all protection, including AV exclusion. The knowledge and effort required to take precautions and verify files properly is higher than with common threats and the potential consequences much more severe.
Aside from the disabled Windows features, even if you trust the authors of the hypervisor driver and even compile it yourself from source, a serious vulnerability in its code could instantly provide maximum and undetectable access to your system.
Whether that game is worth the risks is something you will ultimately have to decide for yourself.
What’s inside those cracks?
Basically, every modern Hypervisor bypass/crack consists of two parts:
- VBS.cmd: special command-line script, which checks your existing settings and modify them to make your system prepared for HV-cracks.
This script is universal for all HV-games and is developed separately, it doesn’t depend on actual game cracks. You can download the latest version below:
- The Crack/Bypass itself
Consists of EXEs/DLLs, which does the actual Denuvo bypassing + other additional DLLs, like Goldberg Steam emulator to get past the underlying Steam protection.
Those files work only for specific game versions, for which they were made. They won’t work on different game version or other games.
Other Software Updates
Solves the PC restart issue on some systems, mostly on Intels. This a mirror from this official GitHub page.
The older version of “hypervisor-launcher.exe” is used in many DenuvOwO releases and in some of my repacks released before March 28, 2026. All HV-repacks past with date with this launcher version are using the updated build. You may download and try the new version ONLY if you have a launch issue, no need to replace it if everything works for you.
My repacks with older version “hypervisor-launcher.exe”:
Pre-requirements
Your CPU must support one of two virtualization techniques: VT-x for Intel and AMD-V (SVM) for AMD.
Google if CPU model supports virtualization to know if you can play HV-games.
Before proceeding with HV cracks, check your BIOS for enabling those technologies.
Do I need to disable Secure Boot or use EfiGuard?
No. Current HV bypasses do not require those changes.
