Winols 451 Vmware Fix (90% Simple)

In many cases, the error 451 will now disappear. Chapter 4: Advanced Fix – Hardware Agnostic Mode If the basic .vmx edits don’t work, WinOLS 451 might still be detecting VMware via the CPUID instruction. You need hardware-agnostic masking . Additional .vmx Parameters Add these lines to your .vmx file:

# Disable VMware backdoor I/O port isolation.tools.setVersion.disable = "TRUE" isolation.tools.getVersion.disable = "TRUE" monitor_control.restrict_backdoor = "TRUE" smbios.reflectHost = "TRUE" hw.model = "MacBookPro11,3" bios.vendor = "American Megatrends Inc." bios.version = "5.11" Disable VMware-specific CPUID cpuid.1.ecx = "0:----:---:---:----:----:----:----:----" cpuid.1.edx = "---:----:---:----:----:----:----:----:----" Hide VMware from DMI/SMBIOS tables SMBIOS.noOEMStrings = "TRUE" mce.enable = "TRUE" Fake disk and network vendor strings disk.enableUUID = "FALSE" ethernet0.virtualDev = "e1000e" winols 451 vmware fix

These parameters are known to defeat the most common anti-VM checks in WinOLS 451: In many cases, the error 451 will now disappear

# Disable hypervisor CPUID leaf hypervisor.cpuid.v0 = "FALSE" cpuid.coresPerSocket = "1" Remove hypervisor bit from CPUID cpuid.1.ecx = "0:---:-:----:----:----:----:----:--0:----" cpuid.80000001.ecx = "0:----:----:----:----:----:----:----:----" Additional isolation flags monitor_control.disable_directexec = "TRUE" prefvmx.minVmMemPct = "100" Additional

If you still experience issues, consider switching to with VBoxVGA graphics and disabling the Guest Additions – but the community generally agrees that VMware Workstation with the above patches offers the best stability for ECU tuning workflows.
