    VMware WS Pro 17:  These steps will most likely still be required on Win 11 Pro with Secure Boot enabled. (More testing in progress)

    I have seen a few support requests lately reference the issues with VMware Workstation Player and Pro on Windows 11. 

    Generally, it seems that when trying to start the an error message is presented regarding the lack of VT-x (Intel CPU) or AMD-v (AMD CPU), and would you like to continue booting the VM without.

    • This procedure was tested on an AMD Ryzen 9 5950X 16-Core Processor 3.40 GHz with Windows 11 Pro and VMware WS Player as well as Pro version 17.
    • No guarantee nor warranty is provided with this procedure and no liability is tied to the person posting this procedure, nor anyone associated with VMware
    • This procedure will disable any ability to use Hyper-V.
    • This procedure will disable specific additional security features provided by Windows - USE AT YOUR OWN RISK.
    • This procedure was designed and tested for use PRIOR to installing VMware WS Player or Pro.

     

    NOTE: This procedure will most likely not work if done after installing VMware, as when installing VMware prior, it will default to Hyper-V as it's underlying hypervisor and will not automatically change hypervisor's after install.

     

    NOTE: After installing WMware workstation, please open VMware Workstation:

    1. Edit->Preferences
    2. Change the default save location for virtual machines to a folder that is NOT being synced with MS OneDrive

    By default, Windows 11 now has "My Documents" linked to your OneDrive folder. This is not a case of syncing the contents of your folder, but the folder IS the OneDrive folder.
