Windows 10 and Windows 11 are vulnerable to a local elevation of privilege vulnerability after discovering that users with low privileges can access sensitive Registry database files. The database files associated with the Windows Registry are stored under the C:Windowssystem32config folder and are broken up into different files such as SYSTEM, SECURITY, SAM, DEFAULT, and SOFTWARE. As these files contain sensitive information about all user accounts on a device and security tokens used by Windows features, they should be restricted from being viewed by regular users with no elevated privileges.
Many of the hardware and software security features Microsoft lists as absolute requirements for a successful Windows 11 installation are already available as options in Windows 10. In some cases, getting these more advanced levels of security is just a matter of turning them on, particularly on newer PCs. One of the more powerful of these security features is the Hypervisor-Protected Code Integrity protocol.
