Why Hyper-V Breaks Emulators on Windows 11 (And the Fix)

Enabling Hyper-V on Windows 11 can cause applications like BlueStacks or VirtualBox to lag or fail to launch due to conflicts with CPU virtualization extensions (VT-x/AMD-V). Hyper-V is a Type-1 hypervisor that monopolizes these resources, preventing Type-2 hypervisors from accessing them directly. Common issues include error messages from BlueStacks, LDPlayer, VirtualBox, VMware, and Android Studio related to virtualization availability. To check if Hyper-V is enabled, users can use Task Manager, System Information, Windows Features, Command Prompt, or PowerShell. Disabling Hyper-V can be done through various methods, including unchecking it in Windows Features, using PowerShell, the bcdedit command, or modifying BIOS settings. However, disabling Hyper-V also stops functionalities like WSL2 and Memory Integrity. Some modern emulators, such as BlueStacks and VMware Workstation Pro, have adapted to work alongside Hyper-V, while VirtualBox's compatibility remains experimental. For optimal emulator performance, users should allocate appropriate CPU cores and RAM, ensure virtualization is enabled in BIOS, enable GPU acceleration, and set the Windows power plan to "Best performance." If issues persist, users should confirm Hyper-V is off, check BIOS settings, and reset emulator configurations.

Linux and Windows 95 running side by side? This dev made it happen.

Open-source developer "Hailey" has introduced the Windows 9x Subsystem for Linux (WSL9X), which allows users to run both Windows and Linux applications simultaneously on classic versions of Windows, including Windows 95, 98, and Me. WSL9X operates by running a modern Linux kernel (6.19) alongside the Windows 9x kernel, enabling features such as paging, memory protection, and pre-emptive scheduling. It is neither emulation nor virtualization and does not require hardware virtualization. WSL9X is available for download, but users must build it from the source provided by Hailey. It allows access to a genuine Linux terminal alongside classic Windows applications, enabling various tasks without compromising system stability.

Get Linux on your ancient 486 Windows 95 desktop using WSL9x — very old Windows PCs can cooperatively run very modern Linux kernels

A computer enthusiast has developed a tool called WSL9x, which allows users to run contemporary Linux kernels on early versions of Windows (from Windows 95 onward) and on machines with 486 CPUs. WSL9x enables the simultaneous operation of Windows and Linux applications without relying on hardware virtualization. The architecture includes a client program, wsl.com, which manages a DOS window for the console driver. Meanwhile, the Linux community is phasing out support for the Intel 486 CPU, with developers removing related support options in the Linux kernel, marking the end of support for this processor.

How to disable Hyper-V for Windows 11

Microsoft's Hyper-V is a hardware virtualization platform integrated into Windows 11 Professional, Enterprise, and Education editions, allowing users to host multiple virtual machines (VMs) on a single computer. It operates using a type 1 hypervisor directly on hardware, enabling VMs to share resources like CPU, memory, and storage. Hyper-V includes features such as dynamic memory allocation, software-defined networking, and saved checkpoints. IT administrators may need to disable Hyper-V due to compatibility issues with third-party virtualization software, high-precision applications, or driver conflicts. Disabling Hyper-V can also affect security features reliant on it, such as virtualization-based security (VBS) and Device Guard. Methods to disable Hyper-V include: 1. Using the Windows Features dialog. 2. Executing a PowerShell command: Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All, HypervisorPlatform, VirtualMachinePlatform. 3. Running a DISM command:

dism /Online /Disable-Feature /FeatureName:Microsoft-Hyper-V-All /FeatureName:HypervisorPlatform /FeatureName:VirtualMachinePlatform

. 4. Using the bcdedit command: bcdedit /set hypervisorlaunchtype off. 5. Modifying Group Policy to disable VBS. 6. Editing the Windows Registry to disable VBS or Credential Guard. For multiple managed computers, administrators can create and execute a PowerShell script or use Group Policy Objects to streamline the process. Testing in a controlled environment is recommended to ensure desired outcomes without compromising security or functionality.

Windows 11 ends Android app support: practical workarounds

Microsoft has discontinued the Windows Subsystem for Android and its integration with the Amazon Appstore on Windows 11 due to low demand. Users can no longer use an official Microsoft method to install general Android apps. The primary alternatives are Google Play Games on PC, which focuses on gaming, and third-party emulators like BlueStacks, LDPlayer, and GameLoop for a broader range of applications. To use Google Play Games, users need a PC with at least 8 GB RAM, a modern quad-core processor, hardware-accelerated graphics, SSD storage with 10 GB free, and hardware virtualization enabled. Users must enable virtualization in their UEFI or BIOS settings and activate the Virtual Machine Platform and Windows Hypervisor Platform in Windows. Emulators allow users to run full Android apps on Windows. They can download apps from the Google Play Store within the emulator or sideload APK files. Users should be cautious about security risks when sideloading apps and stick to reputable sources. Performance tuning for emulators involves allocating sufficient resources, resolving virtualization conflicts, and optimizing settings like resolution and frame rate. Users are advised to install on SSDs and minimize background tasks for better performance.

Russian hackers abuse Hyper-V to hide malware in Linux VMs

The Russian hacker group Curly COMrades has been using Microsoft Hyper-V to bypass endpoint detection and response (EDR) solutions by creating a concealed Alpine Linux-based virtual machine for running malware. They have deployed proprietary tools, CurlyShell and CurlCat, within this virtual environment to maintain operational stealth and secure communication. Active since mid-2024, the group targets government and judicial entities in Georgia and energy companies in Moldova. In early July, they gained remote access to two machines, activated Hyper-V, and disabled its management interface to deploy a minimalistic virtual machine that hosted their malware. This tactic allowed them to evade traditional host-based EDR detections. The virtual machine was configured to use the Default Switch network adapter, making malicious traffic appear to originate from the legitimate host's IP address. CurlyShell executes commands and maintains persistence, while CurlCat facilitates covert traffic tunneling. The group also utilized PowerShell scripts for persistence and pivoting to remote systems, including injecting Kerberos tickets into LSASS and creating local accounts via Group Policy. Bitdefender advises organizations to monitor for abnormal Hyper-V activation, LSASS access, and suspicious PowerShell scripts.

6 Windows hardening steps that don’t break gaming or DRM

Windows 11 is not the most secure operating system by default but offers ways to enhance security without affecting gaming performance. Gaming PCs are vulnerable to cyber threats and should adopt security measures. Customizing Windows Firewall allows users to maintain internet access for gaming applications while ensuring security. Users should add key game executable files to the "allowed apps" list and consider using SimpleWall for better control over network activity. Using a standard account for gaming sessions enhances security by limiting admin account access, which should be reserved for software installation and updates. Implementing multi-factor authentication for both admin and standard user accounts adds an extra layer of security. Windows Defender has improved and can be an efficient antivirus option, but third-party solutions may conflict with gaming performance. Game files should be added to Windows Defender's exclusion list to avoid performance issues. Disabling unnecessary Windows services can enhance security and performance by reducing the attack surface and freeing up resources. Common services to disable include Cellular Time, Connected Devices Platform Service, and Telemetry. Secure Boot protects against malicious software during the boot process and may require BIOS adjustments. It does not affect gaming performance and is often necessary for games with kernel-level anti-cheat systems. Memory Integrity and Core Isolation are advanced security features that protect against low-level attacks by creating an isolated environment for critical processes. These features require minimal resources if the CPU supports Intel's Mode-Based Execution Control (MBEC) or AMD's Guest Mode Execution Trap (GMET). Balancing security measures with optimal system performance is essential for a secure gaming experience.
