    Hi atharv raut,

    The error 0x80240021 you’re seeing when trying to enable Virtual Machine Platform usually points to an issue with Windows Update components or prerequisites not being fully met. First, make sure you’re running Windows 11 Pro or Enterprise, since Virtual Machine Platform isn’t supported on Home editions. Next, check that virtualization is enabled in your BIOS/UEFI (look for Intel VT-x or AMD-V settings) and that Hyper-V is turned on in Windows Features.

    If those prerequisites are in place, try running Windows Update Troubleshooter and then reattempt the installation. You can also reset the Windows Update components by running DISM /Online /Cleanup-Image /RestoreHealth followed by sfc /scannow in an elevated command prompt. Another common fix is to install the latest cumulative updates, as missing patches can block optional feature installs. If the issue persists, you may want to manually add the feature using PowerShell with Enable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform -All.

    In short, the error isn’t about your request being invalid, but rather about Windows not being able to complete the feature install due to update or prerequisite checks.

    Give these steps a try and let me know how it goes. If you find this answer helpful, kindly hit “accept answer”
