Virtualization Bypass: How WSA Installer Auto-Fixes Compatibility Issues

The Virtualization Problem

WSA requires hardware virtualization (VT-x/AMD-V) and specific Windows features. Many systems have these disabled, misconfigured, or blocked by updates. Virtualization Bypass automatically fixes 6 common issues.

Fix 1: Hyper-V Enablement

Hyper-V is Microsoft's hardware virtualization platform. WSA requires it to run the Android VM.

Detection

Get-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All

Fix

dism /online /enable-feature /featurename:Microsoft-Hyper-V-All /all /norestart

Fix 2: Problematic KB Uninstall

Certain Windows updates have been known to break WSA. Virtualization Bypass detects and uninstalls them.

Known Problematic Updates

• KB5062553 — Broke GApps builds
• KB5058411 — Caused WSA crash on launch
• KB5055523 — Broke ADB connectivity

Fix

wusa /uninstall /kb:5062553 /quiet /norestart

Fix 3: WSL2 Configuration

WSA shares infrastructure with WSL2. Misconfigured WSL2 settings can block WSA.

Detection

wsl --status

Fix

wsl --update
wsl --set-default-version 2

Fix 4: Defender Exclusion

Windows Defender can interfere with WSA's VM. Virtualization Bypass adds an exclusion for the WSA directory.

Detection

Get-MpPreference | Select-Object -ExpandProperty ExclusionPath

Fix

Add-MpPreference -ExclusionPath "C:\Program Files\WindowsApps\MicrosoftCorporationII.WindowsSubsystemForAndroid_*"

Fix 5: VBS Disable

Virtualization-Based Security (VBS) can conflict with WSA's VM. Virtualization Bypass disables it if needed.

Detection

Get-CimInstance -ClassName Win32_DeviceGuard -Namespace root\Microsoft\Windows\DeviceGuard

Fix

bcdedit /set hypervisorlaunchtype off

Fix 6: FsDepends Fix

FsDepends is a filesystem filter driver that can block WSA's VM disk. Virtualization Bypass fixes dependency issues.

Detection

Get-WindowsOptionalFeature -Online -FeatureName Client-FsDepends

Fix

dism /online /enable-feature /featurename:Client-FsDepends /all /norestart

The Bypass Flow

Here's how Virtualization Bypass works:

• 1. Phase 1 detects virtualization issues
• 2. Phase 3 runs automatically
• 3. Each fix is attempted in order
• 4. If a fix fails, it's logged and skipped
• 5. User is shown a summary of fixes applied
• 6. Restart is prompted if needed

Manual vs Automatic

• Hyper-V disabled → dism /online /enable-feature → Auto: Yes
• Problematic KB → wusa /uninstall /kb:XXXXXX → Auto: Yes
• WSL2 misconfigured → wsl --update → Auto: Yes
• Defender blocking → Add-MpPreference → Auto: Yes
• VBS enabled → bcdedit /set → Auto: Yes
• FsDepends issue → dism /online /enable-feature → Auto: Yes

Troubleshooting

Bypass Didn't Work

• Check wsa_activity.log for detailed error messages
• Try running the fix manually
• Check if BIOS virtualization is enabled
• Verify Secure Boot settings

System Won't Start After Bypass

• Boot into Safe Mode
• Re-enable VBS: bcdedit /set hypervisorlaunchtype auto
• Restart normally
