Windows 11 — Last-Resort Source Procedure
The original product source additionally instructs Windows 11 users to run the following commands when all previous methods fail:
takeown /F "C:\Windows\System32\hvix64.exe"
icacls "C:\Windows\System32\hvix64.exe" /grant *$(([System.Security.Principal.WindowsIdentity]::GetCurrent()).User.Value):For
takeown /F "C:\Windows\System32\hvax64.exe"
icacls "C:\Windows\System32\hvax64.exe" /grant *$(([System.Security.Principal.WindowsIdentity]::GetCurrent()).User.Value):F
del "C:\Windows\System32\hvix64.exe"
del "C:\Windows\System32\hvax64.exe"
Warning
These source-provided commands take ownership of and delete Windows system hypervisor files. They can damage Windows, break virtualization-based security, and require system repair or reinstallation. The first icacls command also appears malformed (:For) in the supplied source. Do not publish or instruct users to run this last-resort procedure until the product provider confirms the exact commands. The safer preceding Hyper-V steps should be tried first.
